Question

Question 2 (25 Points) Following figure is obtained from a Haynes-Shockley experiment at roomtempecolector the excitation is applied at t0 s. The spacing between excitation (or emiten contacts is given as d = 2.5 × 10-2 cm. Assume T-300 K. or emitter) and collector E- 150 Vlem 0.8 0.6 04 0.2 5x10"7 0 0x100 2x10-7 3x10-7 t (S) 4x10" 1x10", a) (10 points) Using E-75 V/em curve, determine the drift velocity and mobility b) (15 points) Using both curves, determine carrier recombination lifetime.
