Abstract
This article is devoted to the issues of numerical simulation of field Hall sensors (FHSs) based on the silicon-on-insulator (SOI) structure with two control gates. To solve the problem, a two-level local-one-dimensional computational model is used. At the first level, a series of one-dimensional Schrödinger–Poisson equations, which describe the distribution of the density of charge carriers across the heterostructure in different sections, are solved. The received information is transferred to the second level, where the current characteristics of the element are calculated. The numerical simulation results are compared with the experimental data obtained for FHSs. Comparative analysis shows close agreement between the calculated and experimental data. The developed computer model makes it possible to quickly carry out a multivariate analysis of various FHS structures, which creates the base for optimizing devices of the class under consideration.
