Overview
Electrical mobility is the ability of charged particles (like electrons or ions) to move through a medium in response to an electric field that is pulling them.
💡
Pro Tips
Formula: μ = vd / E.
The SI unit is m²/(V·s), but cm²/(V·s) is very common in semiconductor physics.
Mobility depends on the type of charge carrier, the material, and the temperature.

Fun Facts
"In semiconductors, electrons usually have higher mobility than 'holes'."
"Mobility is limited by scattering with impurities or the crystal lattice (phonons)."
"Gallium Arsenide (GaAs) has much higher electron mobility than Silicon (Si), making it better for high-speed electronics."
