In this work, an SBD based on EFG Ga2O3 crystal substrate is fabricated and characterized. Electrical parameters such as Ron, φB, n, Rs, and Nd are extracted systematically by analyzing J-V and C-V curves of the device. The detailed measurements and theoretical analysis are presented in this paper.
In this work, a Schottky barrier diode (SBD) is fabricated and demonstrated based on the edge-defined film-fed grown (EFG) Ga2O3 crystal substrate. At the current stage, for high resistance un-doped Ga2O3 films and/or bulk substrates, the carrier concentration (and other electrical parameters) is difficult to be obtained by using the conventional Hall measurement. Therefore, we extracted the electrical parameters such as on-state resistance (R-on), Schottky barrier height (phi(B)), the ideal factor (n), series resistance (R-s) and the carrier concentration (N-d) by analyzing the current density-voltage (J-V) and capacitance-voltage (C-V) curves of the Ga2O3-based SBD, systematically. The detailed measurements and theoretical analysis are displayed in this paper.
