Consider a Silicon semiconductor doped with NA=[aman]*10^[aexp] cm^-3 and ND=[dman]*10^[dexp] cm^-3. Calculate the value of the conductivity given a hole mobility of [hmob] cm^2/Vs and an electron mobility of [emob] cm^2/Vs. Confirm using unit analysis that the resulting units are 1/ohm-cm.

Consider the vacuum tube below with a positive voltage on the right hand plate, and the left plate exposed to light. The work function of the plates is 3 eV. You may assume h=4×10^-15 eV s and c=3×10^8 m/s. a) If a photon of 350 nm wavelength interacts with the plate, an electron will be released T/F? Justify your ans on your show your work sheet?
