Electric-Field Modulation of Thermopower for the KTaO3 Field Effect Transistors

Akira Yoshikawa, Kosuke Uchida, Kunihito Koumoto +3

We show herein fabrication and field-modulated thermopower for KTaO3 single-crystal based field-effect transistors (FETs). The KTaO3 FET exhibits field effect mobility of ~8 cm2/Vs…
