a The schematic illustration of the 2D Ga2O3 based FETs. b The circuit diagram where the MSM configuration can be modeled by two back-to-back Schottky diodes, including a forward-biased and a reverse-biased diode, connected in series with a resistor. c An experimental dark I–V characteristic curve plotted with the thermionic emission fit. Good consistency between the experimental and fitted data indicates that the thermionic emission theory entirely supports electron transmission.
