National Cheng Kung University in Taiwan is experimenting with piezoelectric gated thin-film transistors. “Piezotronic force sensors are typically governed by either a strain-induced Schottky barrier height modulation or by a piezo-gating effect that redistributes the charge carriers in an induced piezoelectric field,” according to NCKU. “While Schottky barrier height based piezotronic devices have been well-explored, …
