A laser beam with a power of 200 mW and frequency v= 15 x 1014 Hz is incident on a Si photo- with Na = 1 x 1012 cm3 fully ionized with an absorption coefficient as = 1 x 10 cm1. At steady state and assuming the electrons and holes recombination life times are T = To = 1 ns. Based on that calculate the total concentration of holes (p) in the valence band. Select one: O A.P = 2.01e12 /cm^3 OB. P = 2.25e15 /cm^3 • C.P = 2.25e16 /cm^3 OD. P = 2.25e18 /cm^3 E. P = 2.25e17 /cm^3 Clear my choice diotitra recomhination efficiency) n
