STEP 0: Pre-Calculation Summary

Formula Used

Charge Carriers Mobility = Drift Speed/Electric Field Intensity
μ = V_d/E_I
This formula uses 3 Variables

Variables Used

Charge Carriers Mobility - (Measured in Square Meter per Volt per Second) - Charge Carriers Mobility is defined as the magnitude of their drift velocity per unit applied electric field.
Drift Speed - (Measured in Meter per Second) - The drift speed is the average speed that a particle achieves due to an electric field.
Electric Field Intensity - (Measured in Volt per Meter) - Electric Field Intensity refers to the force per unit charge experienced by charged particles (such as electrons or holes) within the material.

STEP 1: Convert Input(s) to Base Unit

Drift Speed: 10.24 Meter per Second --> 10.24 Meter per Second No Conversion Required
