Abstract

Transparent and flexible thin film transistors (TFTs) with channel layers composed of sintered HgTe nanocrystals were fabricated on top of UV/ozone treated plastic substrates and their electrical properties were characterized. A representative TFT with a channel layer composed of sintered HgTe nanocrystals revealed typical p-type characteristics, an on/off current ratio of ∼10 ³ and a field-effect mobility of 4.1 cm² V^-1 s^-1. When the substrate was bent until the bending radius of the substrate reached 2.4 cm, which corresponded to a strain of 0.83% that the HgTe thin film experienced, the TFT exhibited an on/off current ratio of ∼10 ³ and a field-effect mobility of 4.0 cm² V^-1 s^-1.
