write a Program to model random motion of electron
显示 更早的评论
I am having difficulty in writing a program to model random motion of electron. The main problem here is that I want to assign each particle a random location in x-y plane with the extent of the silicon. The extent is 200nm by 100nm.
clc
clear all
LR = 200e-9; %Length of region
BR = 100e-9; %Breadth of region
numParticles = 1000;% no of particles
numSteps = 1;
x = zeros(numParticles, numSteps);
y = zeros(numParticles, numSteps);
xx = 0:0.2e-9:200e-9;
yy = 0:0.1e-9:100e-9;
h = meshgrid(xx,yy);

You can use randi to place the 'electrons' at random points on the grid by picking the grid indexes at random. The distribution will be uniform and permit overlaps. If you need unique particle locations, you'll need to use randperm instead.

xx = 0:0.2e-9:200e-9;
yy = 0:0.1e-9:100e-9;
size_x = numel(xx);
size_y = numel(yy);
xindex_Particles = randi(size_x,[numParticles,1]);
yindex_Particles = randi(size_y,[numParticles,1]);
xy_Particles = [xx(xindex_Particles)', yy(yindex_Particles)'];
xy_Particles(1:5,:)
