Analyze Operational Mechanism Of Organic Static Induction Transistor And Optimize Structure Parameters

In order to comprehend schottky gate of organic static induction transistor, chapter two expatiates characteristics of PN junction and schottky junction. In order to comprehend operational principle and characteristics of organic static induction transistor, chapter three expatiates operational principle and characteristics of junction field effect transistor and static induction transistor. According to the basic idea of finite element method constructs computer procedure to solve the poisson equation . For the sake of fully analysis operational mechanism of organic static induction transistor prepares for the theories fundament.After organic static induction transistor manufactured succeedly, have not been earring through expounding and demonstrating systematically in theory. The main work of this thesis analyzes the organic static induction transistor's operational mechanism, and researchs the change of gate length, change of gate-drain distance and change of electric channel breadth for operational characteristics influence of organic static induction transistor.First, according to the actual organic static induction transistor establishing the physical model and selecting appropriate structure parameters, solves poisson's equation by adopting finite element method. Next, basing on discrete electric potential, plots the distributing figure of the electic potential and electic field , and analyzes relationship between the operational characteristics of static induction transistor and the structure parameter and bias voltage.This thesis probes beneficially into numerical calculating and analyzing of the two-dimension model of organic static induction transistor by adopting finite element method, and builds theory foundation for further analyzing systematically operational mechanism of organic static induction transistor and optimizing design of structure parameters for the future.
