Answer:
Mobility of the minority carriers,
Diffusion coefficient for minority carriers,
Verified from Einstein relation as
Explanation:
Length of sample,
Separation between the two probes, L = 1.8 cm
Drift time,
Applied voltage, V = 5 V
Mobility of the minority carriers ( electrons),
Where the drift velocity,
and the Electric field strength,
E = 5/2
E = 2.5 V/cm
Mobility of the minority carriers:
The electron diffusion coefficient,
, where Δt = separation of pulse seen in an oscilloscope in time( it should be in micro second range)
For the Einstein equation to be satisfied,
Verified.
