[#331] A voltage V G is applied across a MOS capacitor with metal gate and p-type silicon substrate at T = 300 K. The inversion carrier density (in number of carriers per unit area) for V G = 0.8 V is 2 × 10 11 cm -2 . For V G = 1.3 V, the inversion carrier density is 4 × 10 11 cm -2 . What is the value of the inversion carrier density for V G = 1.8 V?
Correct Answer
(B) 6.0 × 10 11 cm -2
