Calculate the Eo given that Nd=1.5*10^10cm^-3, Na=1.5*10^10cm^-3 at temperature 300K?(a) 1.5*10^10eV(b) 0.256eV(c) 0eV(d) 4.14*10^-21eVThis question was posed to me in my homework.Origin of the question is Band Structure of an Open-Circuited p-n junction topic in division Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer»

The correct OPTION is (C) 0eV

The best I can explain: Eo=kTln((Nd*Na)/(ni)^2)

Substituting k=1.38*10^-23/K, T=300k and the VALUES ofNd,NAAND ni,

We get

Eo=0eV.
