Variables Used
Sheet Resistance - (Measured in Ohm) - Sheet Resistance is the resistance of a square piece of a thin material with contacts made to two opposite sides of the square.
Charge - (Measured in Coulomb) - Charge a characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons.
Electron Doping Silicon Mobility - (Measured in Square Meter per Volt per Second) - Electron Doping Silicon Mobility characterizes how quickly an electron can move through a metal or semiconductor when pulled by an electric field.
Equilibrium Concentration of N-Type - (Measured in 1 per Cubic Meter) - Equilibrium Concentration of N-Type is equal to the density of donor atoms because the electrons for conduction are solely given by the donor atom.
Thickness of Layer - (Measured in Meter) - Thickness of Layer is often used for manufacturing casted parts to ensure that wall structure is designed with just the right amount of material.
