// Given data
n = 10^15; // doping concentration in /cm^3
er = 15; // relative permitivity
eo = 8.85*10^-14; // permitivity in F/cm
e = 1.6*10^-19; // charge of electron
sigma = 133*10^-2; // conductivity in ohm/cm
// calculations
Td = (eo*er)/sigma // dielectric relaxation time constant
u = sigma/(n*e) // mobility
// Output
