High-speed solution-processed organic single crystal transistors using a novel triisopropylsilylethynyl anthracene derivative

Abstract

A high-quality organic single crystal transistor (OSCT) was fabricated via solution-processing using a novel anthracene derivative (TIPsAntNE). The OSCT fabricated on a surface-modified high-capacitance ZrOx substrate provided a transistor that operated at low voltages with a high mobility up to 4.1 cm(2)/Vs and negligible hysteresis (a V-th shift of <20mV). Importantly, the TIPsAntNE OSCT functioned under a high-frequency AC signal with a gate bias as high as 30 kHz. These are crucial operational requirements for commercial applications of organic transistors. The photoresponsivity (>1 A/W) of the TIPsAntNE single crystal was high over a wide range across the visible spectrum. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4764062]
