Mathematical model and software complex for computer simulation of field emission electron sources

Abstract

A mathematical model of motion of the heart for use in generating source and attenuation maps for simulating emission imaging Med.Abstract. The software complex developed in MATLAB allows modelling of function of diode and triode structures based on field emission electron sources with complex sub-micron geometry, their volt-ampere characteristics, calculating distribution of electric field for educational and research needs. The goal of this paper is describing the physical-mathematical model, calculation methods and algorithms the software complex is based on, demonstrating the principles of its function and showing results of its work. For getting to know the complex, a demo version with graphical user interface is presented.

Confidence complexity of computer algorithms

“…This approach is less general, but it has that advantage that it allows to test the computation speed of whole software complex and derive properties of the algorithm it's based on without having to study employed third-party libraries, packages and mathematical environments separately. We are creating applied software complexes for mathematical and computer modelling of emission sources described with results of their function in [4]- [14]. This paper focuses on developing methods of practical assessment of confidence complexity for the algorithm itself and the software based on it.…”

Modelling of static mode characteristics of a thin-film vacuum nanotriode

“…Modelling of processes described above is a complex task, was carried out in the software complex developed in Matlab and Matlab PDE Toolbox [2][3][4]. Following is description of important aspects of calculation procedure with domain triangulation.…”

“…Electron transport processes are described using electrostatic approximation and hydrodynamic flow function for finite element solution [2][3][4]. …”
