Mr. Robert Maxwell, Human Resources DirectorBronson’s Berry Farm4747 Bronson StreetSan Diego California, 90212

Dear Mr. Maxwell,

I am contacting you in regards to the Blueberry Farmer position you had advertised at the local Farmer’s Market this past Saturday, July 10. With my previous farming experience, extensive knowledge on berry science and genetic manipulation, I would make a valuable addition you company.

My work experience includes owning an operating two of Washington’s most successful berry farms along with working for the past 30 years in the berry production. I was able to create two new and very popular strains of blueberries making them larger and more flavorful than any of the local competitors. My responsibilities as Director of Manufacturing and Production included overseeing all aspects of production and manufacturing including working directly with the engineers in a team-focused environment to introduce new and exciting products.

My education in biology and plant chemistry at the University of Utah will allow me to add significant contributions to your company. As you may know the University of Utah is one of the leaders in plant genetics. During my graduate work I was published in many scientific journals and newspaper articles for my work in improving certain species of blueberry. While at the University I also gained experience working with water seepage systems allowing plants to survive in areas they normally wouldn’t.

I have included my résumé and professional portfolio that further highlights my skills and other qualifications for you to review at your soonest opportunity. If you have any questions or need additional information don’t hesitate to call me at 801-555-2011 or email me at erik.ottley@email.com. Thank you for the opportunity to apply at Bronson’s Berry Farm and I look forward to hearing from you.

Sincerely,

Erik Ottley

What is a Semiconductor?

Semiconductors are an important part of today’s technology

They are created by doping silicon with various elements like arsenic, phosphorus, boron, and gallium

Semiconductor’s unique properties make them perfect for electronic devices

Doping involves turning silicon’s insulating properties into conductive properties

There are two types of silicon doping: p-type and n-type

The first examples of semiconductors were diodes

Semiconductors eventually replaced vacuum tubes

Replica of early transistor

The official definition of a semiconductor is “any of a class of solids (as germanium or silicon) whose electrical conductivity is between that of a conductor and that of an insulator in being nearly as great as that of a metal at high temperatures and nearly absent at low temperature.”[1] What exactly does that mean? First let’s look at the two types of electrical devices that the semiconductor falls between; the insulator and the conductor.

An insulator stops the flow of electricity (or electrons) between two or more objects. Rubber is a very common insulator. This is why it is used on the outside of most wire - it keeps the flow of electricity from escaping until it reaches its destination. A conductor is the exact the opposite of an insulator. The conductor allows the flow of electricity between objects. Copper and gold are very good conductors and are commonly used in electrical devices.

Now back to the semiconductor. Semiconductors are a big part of our life as they are in just about everything around us - computers, cars, TV’s, and even kitchen equipment. Without them we wouldn’t be where we are today. Most of today’s semiconductors are made from silicon. If you were to look up some of silicon’s properties this might come as a surprise because a pure silicon crystal actually resembles more of an insulator than a conductor. Without conductivity, there is no transfer of electrons. This is where the semiconductor and a process called doping come in.

The process of doping can take a non-conductive material such as silicon and change its properties so it will have conductive properties. Doping is the process of adding very small amounts of impurities to the silicon in order to change its properties slightly. There are two methods of doping: N-type and P-type.

P-type involves adding boron or gallium. Both have only three outer electrons. When added into the silicon lattice (which has four electrons) it creates a “hole” where the extra silicon electron has nothing to bond to. The hole can then allow electricity to pass through making the otherwise non-conductive silicon a conductor.

N-type is a similar process adding phosphorus or arsenic to the silicon. Unlike p-type arsenic and phosphorus has five outer electrons. When added to silicon (four electrons) it creates an extra electron which is allowed to move around freely. This extra electron allows the transfer of electricity through the silicon making it a conductor.

This process is where semiconductor gets its name. So what’s so special about a semiconductor and why not just use a conductor in the first place?

Changing the silicon into a conductor isn’t the main reason for using it. It is when these different types of doped silicon are combined. An example of this is a diode seen to the left. Normally a section of wire allows current to flow in either direction. In the example of a diode when both p-type and n-type silicon are placed next to each other electricity will flow in only one direction. Diodes have many applications. One of them is to protect an electronic device when installing a battery backward. Have you ever noticed something not working only to discover the battery has been installed backwards? That is the work of the diode and one of its many uses.

From there the diode progressed into the transistor. Here rather than two layers of silicon material three are stacked together. Depending on the alternating combinations of p-type and n-type the transistor can either be a switch or an amplifier. Picturing this silicon sandwich after reading about the one-way properties of a diode one might think electricity won’t be able to pass through at all. However, since the transistor can act as a switch if a small current is applied to the center layer a much larger current is then able to pass through this sandwich as a whole.

Further building on this process was the silicon chip that could hold thousands of these transistors. Setting up all of the transistors as switches the silicon chip was born making the microprocessor a reality by fitting millions of these transistors onto a single chip. This was one of the most important parts of the progression as without the microprocessor we wouldn’t have computers or cell phones.

The discovery of silicon and its unique doping properties has helped make society what it is today. What once cost hundreds of thousands of dollars and filled a room with vacuum tubes could now be produced inexpensively and extremely compact.

Harness the power of the Hubble Telescope in your pocket....well almost.Have you ever looked up into the night sky wishing you make out the rings of Saturn or Jupiter’s red spot? Well now you can. Pocket Telescopes is proud to announce our newest product - the Pocket Hubble XD2000.1. With its amazing 4,000x zoom you can even view our furthest plan...err dwarf planet Pluto.

Unlike the original Hubble our mirrors undergo an extensive quality analysis review to ensure they are flawless and won’t need an expensive repair weeks after the telescope makes it home. Another great feature of the XD2000.1 lies in the fact that it doesn’t need a rocket or shuttle. All that is required are simple tools like a screw driver and small wrench set.

The most dramatic part of the telescope lies in its Optical Telescope Assembly. This was modeled after the original Hubble Telescope but in a smaller package. Two hyperbolic mirrors, which are known for their stellar imaging properties, are polished to an accuracy of about 30% of a wavelength of visible light. There is only about a 20% difference in mirror finish between the XD2000.1 and most large professional telescopes.

Pocket Telescopes also offers a great option that will be sure to make you the life of the star party. While others are struggling to locate certain constellations, the XD2000.1 has a USB port that permits an iPad or iPhone to be connected directly to the optional imaging motor. This upgrade allows automatic star tracking! Simply enter the desired star or stellar object into you preferred device and the imaging motor will find and center the object.

As you can see, the Pocket Hubble is packed with features that you would normally see on a telescope ten times its size. Either the back yard astronomer or the next Galileo Galilei, the Pocket Hubble will be a sure hit.
