Consider a homogeneously doped n-type semiconductor at 300K. The electron concentration is equal to 105 cm, n= 10"cm³, H,= 1000 cm/V-sec, u,= 500 cm²/V-sec, Tno=2×10's, Tpo=1×10's and the applied electric field is zero. A light beam in x-direction was applied to the sample resulting excess e-h pair of 3×10² cm³ at x-0 (edge of the sample). Assuming steady state, then hole concentration at x=20um is . .×10"cm³. (use kT=0.025eV at 300K) a) b) 3.4 c) 5.1 d) 10.1 e) 15.2
