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.
