ON state
OFF state
In principle… In reality…
Related Applications: SWNT Switches, Sensors, Transistor Arrays
Q: How Can We Achieve Addressable Sites Based on 1 CNT (required to make highest
density memory chips)
A: Chemical Functionalization
Initial Result: Hydrogenation of C60 Buckminsterfullerene
Work Performed at UNH for Collaborators at Northrup Grumman
Northrup Grumman Wanted a Faster, Scalable Process
Innovation: Use Microwave Reactor Reduce Total Reaction Time to 5 minutes
Before Hydrogenation After Hydrogenation
Innovation: Apply Same Chemistry to SWNTs Highly Dispersed Species
30 Seconds 5 Minutes
1 Hour 2 Days
Functionalized SWNTs Stay Well Dispersed Without Added Surfactant
