Question
3. In a sample of InGaAs, the effective electron mass is 3.7 x 10-32 kg and that of holes is 1.8 x 10-31 kg. Estimate the density of carriers in the conduction and valence bands and the total carrier density. Take Eg to be 0.75 eV. [2.05 x 1023 m-3, 2.20 x 1024 m-3 and 3.41 x 1017 m-3] 4. The InGaAs sample of question 3 is used in a p + n diode in which the p-type is doped to 1027 and the n-type to 1025 m-3. Determine the barrier potential. [0.975 V]
