Electronic bridge

Semiconductor-enriched SWNTs are usable in thin-film FETs (TFT) • High switching ratios can be achieved (app. 103) and high drive currents (>1 mA) • They deliver strong photocurrents• They are both photoluminescent and electroluminescent.

These high performance semiconducting SWNT FETs also have demonstrated operating frequencies up to 80 GHz (109 operations per second).
