**Design a rectangular bpiece of Silicon with n = 300cm^-3 at T = 300K. Be specific and quantitative**

**n*p = ni^2**

ni = 5.2 × 1015T3/2 e^(−Eg/2kT) electrons/cm^3

ni = 5.2 × 1015T3/2 e^(−Eg/2kT) electrons/cm^3

**Using the formula above, with Eg = 1.12eV = 1.792x10^-19 J, and k = 1.38x10^-23**

i get ni = 1.0776x10^10 electrons/cm^3

Using the formula n*p = ni^2, i solved for p = 3.87x10^17

i get ni = 1.0776x10^10 electrons/cm^3

Using the formula n*p = ni^2, i solved for p = 3.87x10^17

As far as where to go next, I'm unsure. I sent a message to my prof. asking what exactly he wants for this question, but I haven't received a response yet. Would it be even feasible to attempt to get dimensions for a solid using just these values?
