报告内容简介：
Recently, with the increasing requirements for new functional electronic products, soft, ?exible organic electronics have been extensively studied looking to improve upon traditional inorganic silicon techniques. Much attention has been paid to organic thin film transistors (OTFTs) due to their high mobility, low temperature fabrication, large area application, and low cost production. OTFTs have been used as components in active matrix liquid crystal displays and organic light emitting diodes. Organic inverters (or logic doors) have been considered as one of the key elements in organic ?exible circuits and have drawn more attention because they are ?exible and economic to produce. In this report, soft contact lamination method is introduced in the structure of OTFT. It provides an unconventional method to study anisotropic electrical performance of pentacene deposited onto groove-patterned dielectric layer and tune voltage transfer curves (VTC) of organic inverter by changing source-drain current (Isd) direction and grooves direction. Besides, pressure dependent current-controllable OTFT is also fabricated based on relationship between effective channel length and Isdby adopting a bridge-structured polydimethylsiloxane (PDMS) with deposited source-drain electrode. Due to the elastic property of PDMS, reversible and real-time variable electrical performance is also achieved.
