Intrinsic Carrier Concentration

Go Intrinsic Carrier Concentration = sqrt(Effective Density of State in Valence Band*Effective Density of State in Conduction Band)*exp(-Energy Gap/(2*[BoltZ]*Temperature))

Carrier Lifetime

Go Carrier Lifetime = 1/(Proportionality for Recombination*(Holes Concentration in Valance Band+Electron Concentration in Conduction Band))

Energy of Electron given Coulomb's Constant

Go Energy of Electron = (Quantum Number^2*pi^2*[hP]^2)/(2*[Mass-e]*Potential Well Length^2)

Steady State Electron Concentration

Go Steady State Carrier Concentration = Electron Concentration in Conduction Band+Excess Carrier Concentration

Concentration in Conduction Band

Go Electron Concentration in Conduction Band = Effective Density of State in Conduction Band*Fermi Function

Effective Density of State

Go Effective Density of State in Conduction Band = Electron Concentration in Conduction Band/Fermi Function

Fermi Function

Go Fermi Function = Electron Concentration in Conduction Band/Effective Density of State in Conduction Band

Effective Density State in Valence Band

Go Effective Density of State in Valence Band = Holes Concentration in Valance Band/(1-Fermi Function)

Concentration of Holes in Valence Band

Go Holes Concentration in Valance Band = Effective Density of State in Valence Band*(1-Fermi Function)

Recombination Lifetime

Go Recombination Lifetime = (Proportionality for Recombination*Holes Concentration in Valance Band)^-1

Distribution Coefficient

Go Distribution Coefficient = Impurity Concentration in Solid/Impurity Concentration in Liquid

Liquid Concentration

Go Impurity Concentration in Liquid = Impurity Concentration in Solid/Distribution Coefficient

Net Rate of Change in Conduction Band

Go Proportionality for Recombination = Thermal Generation/(Intrinsic Carrier Concentration^2)

Thermal Generation Rate

Go Thermal Generation = Proportionality for Recombination*(Intrinsic Carrier Concentration^2)

Excess Carrier Concentration

Go Excess Carrier Concentration = Optical Generation Rate*Recombination Lifetime

Optical Generation Rate

Go Optical Generation Rate = Excess Carrier Concentration/Recombination Lifetime

Photoelectron Energy

Go Photoelectron Energy = [hP]*Frequency of Incident Light

Conduction Band Energy

Go Conduction Band Energy = Energy Gap+Valence Band Energy

Valence Band Energy

Go Valence Band Energy = Conduction Band Energy-Energy Gap

Energy Gap

Go Energy Gap = Conduction Band Energy-Valence Band Energy

Valence Band Energy Formula

Valence Band Energy = Conduction Band Energy-Energy Gap
E_v = E_c-E_g

How is Energy Gap Formed?

Each band is formed due to the splitting of one or more atomic energy levels. Therefore, the minimum number of states in a band equals twice the number of atoms in the material.The core electrons are tightly bound to the atom and are not allowed to freely move in the material.

How to Calculate Valence Band Energy?

Valence Band Energy calculator uses Valence Band Energy = Conduction Band Energy-Energy Gap to calculate the Valence Band Energy, The Valence Band Energy formula is defined as situations where electrons (or holes) are transported through the top of the valence band such as in a p-type semiconductor.
