Abstract

HgTe nanocrystal-based thin film transistors were fabricated on flexible polyethersulfone substrates and their electrical properties were characterized. Hydrophilic Al₂O₃ buffer layers were first deposited on the flexible substrates and HgTe nanocrystal films were then formed on top of the buffer layers. A representative top-gate flexible thin film transistor with a channel composed of a HgTe nanocrystal film functioned as a p-channel transistor and exhibited a mobility of ~ 1.20 cm²/V{bullet operator}s and an on/off current ratio of ~ 1 × 10³.
