Pure Silicon semiconductor at 500K has equal electrons and holes (1.5 × 10¹⁶ m^-3). Doping by Indium increases n_h to 4.5 × 10²² m^-3. Calculate the type and electron concentration of doped semiconductor.

Why the valence band in semiconductors is partially empty and the conduction band is partially filled at room temperature?

In an intrinsic semiconductor, the number of conduction electrons is 7 × 10¹⁹ m³. Find the total number of current carriers in the same semiconductor of size 1 cm × 1 cm × 1 mm.

The energy gap of silicon is 1.14 eV. What is the maximum wavelength at which silicon will begin absorbing energy?

The energy of a photon of sodium light (λ = 589 nm) equals the bandgap of semiconducting material. Find:

The minimum energy E required to create a hole-electron pair. (5890 A⁰)

The value of E/kT at a temperature of 300 K. (81)

A P-type semiconductor has acceptor level 57 meV above the valence band. What is the maximum wavelength of light required to create a hole? (217100 A⁰)
