A small concentration of minority carries is injected into a homogeneous semiconductor crystal at one point. An electric field of 10 V. cm is applied acoss the crystal and this moves the minority carriers a distance of 1 cm is 20 `mu` sec. The mobility (in cm2 / volt.sec) will be
given E=10V/CM.......and mobility=v/E,WHERE,v is velocity=d/t,
given d=1cm,t=20...........put the value and get the answer i.e.5000.
not answer is already in cm.not need to modify.
Mobility=(velocity of electronics/electric field applied)
Given E=10 , Distence=1 cm , time=20 mu sec =>velocity=(distence/time)=5000 cm/sec
=>mobility=(5000/10)=5000
