Origin of the Threshold Voltage Shift in a Transistor with a 2D Electron Gas Channel at the Al2O3/SrTiO3 Interface

Advanced Electronic Materials, 2020
A transistor is fabricated with a 2D electron gas (2DEG) channel at the Al2O3 (AO)/SrTiO3 (STO) interface. The threshold voltage (Vth) shift of the 2DEG channel in the Pt/AO/2DEG/STO stack induced by negative bias stress is investigated.
