Solved Examples of Semiconductor
Calculate the electron concentration in a silicon semiconductor at room temperature (300 K) assuming the conduction band edge energy (Ec) is:- 1.12 eV and the Fermi energy (Ef) is 0.5 eV.
n = Nc * exp((1.12 eV – 0.5 eV) / (8.6173 × 10^-5 eV/K * 300 K))
(Values of Nc and constants should be looked up in a semiconductor physics reference for accurate calculations.)
d)Drift Current Density (Jd) Formula:
Jd = q * n * μ * E
Where Jd = Drift current density
- q = Elementary charge
- n = Carrier concentration
- μ = Mobility of carriers
- E = Electric field
Calculate the drift current density in a semiconductor with carrier concentration n = 1.5 x 10^16 cm^-3, mobility μ = 1000 cm^2/Vs, and electric field E = 200 V/cm.
Jd = (1.6 x 10^-19 C) * (1.5 x 10^16 cm^-3) * (1000 cm^2/Vs) * (200 V/cm)
= 4.8 x 10^-2 A/cm².
Semiconductors
A Semiconductor is a kind of material that performs conductivity between conductors and insulators and has a conductivity value that lies between the conductor and an insulator.
