Pentacene Organic Thin-Film Transistors on Flexible Paper and Glass Substrates.

摘要

Pentacenebased organic thin film transistors (OTFTs) were fabricated on several types of flexible substrate: commercial photo paper, ultrasmooth specialty paper and ultrathin (100 M) flexible glass. The transistors were fabricated entirely through drystep processing. The transconductance and field effect mobility of OTFTs on photo paper reached values of approximately 0:52 mS m(exp -1) and approximately 0:1 sq cm V(exp -1)1 s(exp -1), respectively. Preliminary results on the lifetime of OTFTs on photo paper yielded stable transconductance and mobility values over a period of more than 250 h. The comparable characteristics of OTFTs fabricated on widely available, low cost paper and high quality expensive liquid crystal display glass indicate the potential importance of cellulose based electronic devices.
