Flatband schottky front interface
WebJul 1, 2024 · Photoelectrochemical measurements allowed estimation of the optical bandgap, E g, and the flatband potential, U FB, of the oxides. The latter was used to interpret in the frame of amorphous Schottky barrier theory the dependence of the impedance on the electrode potential and on the frequency of the employed a.c. signal. WebSchottky diodes. In this module, you will learn about the simplest semiconductor device, a Schottky diode, which consists of a metal-semiconductor junction. You will apply the drift-diffusion model, solving Gauss' law leading to the depletion layer width, the maximum electric field and capacitance versus voltage relation.
