HELP...
A photoemiting semiconductor has a band gap of 2.26eV.
a) What is its threshold frequency..?
b) If UVL of wavelength 1.05 x 10^-9 m falls on it, with what kinetic energy will photoelectrons be emitted..?
The n-type semiconductor used in a particular solar cell has a work function of 3.9eV.
a) What is the threshold frequency of this semiconductor..?
Thanks
