Question


I am trying to use a nested function so that a user can input any given temperature and find the Ni concentration for a particular element. However my function does not seems to be working. All help is appreciated.
function [NiSi,NiGe,NiGaAs] = concentration(tK) % Chris Lee % Oct. 29. 2017 % This function calculates intrinsic ...

Question


My program is not returning a value of 300. Is there something wrong?
syms t eqn1 = (7.3*10^15)*t^(3/2)*exp(1.12/(2*t*8.62*10^(-5)))==1.5*10^10; solx = solve(eqn1,t)

Question


I am tryng to solve for the intrinsic carrier concentration, ni=BT^(3/2)e^-(Eg/2kT), at a given temperature T. Each time I run my program I get the following results.
syms t t = solve('(7.3*10^15)*t^(3/2)*e^(1.12/(2*t*8.62*10^-5))=1.5*10^10','t') **Results*: t = Empty sym: 0-by-1...
