Na = 10^18 cm^-3 Nd = 10^16 cm^-3 ni = 1.45 x 10^10 cm^-3
1.2 Compare the electron and hole mobilities in silicon at 300 K.
Substituting the values for silicon:
The intrinsic carrier concentration in silicon at 300 K can be calculated using the following equation:
Nc = 2.86 x 10^19 cm^-3 Nv = 3.1 x 10^19 cm^-3 Eg = 1.12 eV k = 8.62 x 10^-5 eV/K T = 300 K
Vth = Vtn + γ * (√(2φf + Vsb) - √(2φf))
The current-voltage characteristics of a BJT can be described by the Ebers-Moll model. The collector current can be expressed as:
The threshold voltage of a MOSFET can be calculated using the following equation:
