Question

COURSE: Material Physics

4. A semiconductor has a length L_x = 1 cm, width W_y = 0.01 cm, thickness d_z = 0.001 cm. Electric current flows at I_x = 1 mA when given a potential difference of V_x = 12.5 V. When a magnetic field of Bz = 5 × 10^-2 T is applied, the Hall potential difference reading is V_H = -6.25 mV.

Determine:

a. Concentration of majority carriers!

b. Majority carrier mobility!
