user mobility calculation in matlab

main.m
% Define constants
q = 1.6e-19; % electron charge (C)
kB = 1.38e-23; % Boltzmann constant (J/K)
T = 300; % temperature (K)
n = 1e15; % carrier concentration (cm^-3)
mu = 1000; % mobility (cm^2/Vs)

% Calculate resistivity
rho = 1 / (q * n * mu);

% Calculate conductivity
sigma = 1 / rho;

% Calculate diffusion coefficient
D = kB * T / (q * mu);

% Calculate drift velocity
vd = mu * E;

% Calculate carrier lifetime
tau = L^2 / (D * pi^2);

% Calculate mobility
u = vd / (E / L);
