3. Calculate and plot log(n) (n in cm 3) versus Etop (in ev) (Ec S Etop S Ec+0.3 eV), where Etop is defined in the equation 47(2m* ) 312 Elop JE -E. N mp n = dE; EF = E; + kT In E + Ev + 3 KT In h 3 Ec 1 + exp[(E - EF)/ KT] n ; 2 mn Use Ev = 0, Ec= 1.1 eV, mp = 0.81mo, mn = 1.18mo, ND= 10 5 cm , ni= 1010 cm], T= 300 K. You need to do a "units" check to obtain the correct units for gc(E) and E. Do not mix eV and J. It's best to work in mks units and then convert to cm" at the end. 4. Calculate and plot E-Ec versus go(E)f(E) (it should have the shape below). Use mn = 0.7mo, Ec = 1.2 eV, Ev = 0, EF = 0.9 eV, T= 300 K, O
