//To Calculate the Resistivity of n type semiconductor
//Example 45.2
clear;
clc;
e=1.6*10^-19;//charge on an electron in Coloumbs
ne=8*10^19;//Density of Conduction Electron per metre^3
ue=2.3;//Mobility of Conduction Electron in m^2/V-s
nh=5*10^18;//Density of holes per metre^3
uh=10^-2;//Mobility of holes per m^2/V-s
c=e*((ne*ue)+(nh*uh));//Conductivity of the Semiconductor in C/(m-V-s)
rho=1/c;//Resistivity of Semiconductor in ohm-metre
printf("Resistivity of the n-type semiconductor = %.3f ohm-m",rho);//The answer provided in the textbook is wrong
