Semiconducting Devices and Photovoltaics

Kanicki616) has recently published an extensive review of the semiconducting properties of polyacetylene. We will summarize the field only briefly here. 

A polyacetylene field-effect transistor has been described622 but the response time is slow, apparently because the carrier mobility is low. An FET has been made from polythiophene but source-drain currents were less than 20 nA for drain voltages up to 50 V. The hole mobility was very low, calculated to be 2 x 10 5 cm2 V-1 s 1 623).
