Band-like electron transport in organic transistors and implication of the molecular structure for performance optimization

Adv Mater. 2012 Jan 24;24(4):503-8. doi: 10.1002/adma.201103960. Epub 2011 Dec 27.

Abstract

The Hall effect and an increase of field-effect mobility with decreasing temperature is observerd in n-channel single-crystal organic field-effect transistors (OFETs). A quantitative analysis of these findings, together with results on different p-channel transistors, indicate the importance of the semiconductor molecular polarizability and the structure of the charge transport layers in the crystal for the observation of band-like transport in OFETs.
