Abstract

In the present study, a quasi-vertical diamond Schottky barrier diode (SBD) with a junction termination extension (JTE) structure is designed and simulated using Silvaco software. We firstly investigate the influences of spatial location and thickness of the n-Ga₂O₃/p-diamond PN junction on the electrical performances. Subsequently, the doping concentration and width of the JTE region are optimized to achieve the highest Baliga Figure of Merit (BFOM) value, with the underlying mechanisms governing the electrical characteristics systematically analyzed. Furthermore, we also propose a sidewall-enhanced JTE structure to improve the breakdown voltage without influencing the on-resistance and turn-on voltage. In addition, it is found that the etching depth of the mesa presents minimal influence on the diamond SBD. These findings are beneficial to realizing a high-performance quasi-vertical diamond SBD.

期刊介绍： Prediction through modelling forms the basis of engineering design. The computational power at the fingertips of the professional engineer is increasing enormously and techniques for computer simulation are changing rapidly. Engineers need models which relate to their design area and which are adaptable to new design concepts. They also need efficient and friendly ways of presenting, viewing and transmitting the data associated with their models. The International Journal of Numerical Modelling: Electronic Networks, Devices and Fields provides a communication vehicle for numerical modelling methods and data preparation methods associated with electrical and electronic circuits and fields. It concentrates on numerical modelling rather than abstract numerical mathematics. Contributions on numerical modelling will cover the entire subject of electrical and electronic engineering. They will range from electrical distribution networks to integrated circuits on VLSI design, and from static electric and magnetic fields through microwaves to optical design. They will also include the use of electrical networks as a modelling medium.
