Abstract

This article introduces a modeling method for the reverse biased electric field of junction barrier Schottky (JBS) diodes, utilizing the Schwarz-Christoffel transformation. Building upon prior research on JBS diodes electric field modeling, this approach is rooted in a purely theoretical derivation, avoiding the dependence on conclusions from simulation software—a limitation of earlier modeling methods. In this study, complex boundary conditions are transformed mathematically into simpler ones to make it possible to solve for the electric field. Then, the analytic solution of the electric field distribution is obtained by using the superposition theorem. To validate this modeling method, the electric field distribution from this model is compared with results from simulation software, and a way of applying the analytic solution of the electric field distribution in commercial simulation software is given.

基于Schwarz-Christoffel变换的JBS二极管反向偏置电场建模方法

本文介绍了一种利用Schwarz-Christoffel变换对结势垒肖特基（JBS）二极管反向偏置电场进行建模的方法。基于先前对JBS二极管电场建模的研究，该方法基于纯粹的理论推导，避免了对仿真软件结论的依赖-这是早期建模方法的局限性。在本研究中，复杂的边界条件在数学上转化为简单的边界条件，使求解电场成为可能。然后，利用叠加定理得到了电场分布的解析解。为了验证该建模方法，将该模型的电场分布与仿真软件的结果进行了比较，并给出了一种在商业仿真软件中应用电场分布解析解的方法。
