Organic Phototransistors: High-Performance Phototransistors Based on Single-Crystalline n-Channel Organic Nanowires and Photogenerated Charge-Carrier Behaviors (Adv. Funct. Mater. 5/2013)
On page 629, Hojeong Yu, Zhenan Bao, and Joon Hak Oh report single-crystalline nanowire organic phototransistors (NW-OPTs) fabricated using an n-channel organic semiconductor, N,N'-bis(2-phenylethyl)-perylene-3,4:9,10-tetracarboxylic diimide. Highly sensitive and reproducible photoresponses are observed from the NW-OPTs and photogenerated charge carrier behavior is quantitatively investigated. The findings highlight single-crystalline NW-OPTs as an alternative to conventional thin-film-type photodiodes and could pave the way for optoelectronic device miniaturization.
