Carrier Mobility Calculator
Calculate charge carrier mobility in semiconductors and conductors
About Carrier Mobility
Carrier mobility characterizes how quickly charge carriers move through a material under an applied electric field. Higher mobility means better electrical conductivity for a given carrier concentration.
Key Formulas:
- μ = σ/(ne) (from conductivity)
- μ = vd/E (from drift velocity)
- μ = eτ/m* (from scattering time)
- D = μkT/e (Einstein relation)
Typical Values (300K):
- Si electrons: 1400 cm²/V·s
- Si holes: 450 cm²/V·s
- GaAs electrons: 8500 cm²/V·s
- Graphene: 200,000 cm²/V·s
