How to Calculate Built-in Potential?
Built-in Potential calculator uses Built-in Potential = Thermal Voltage*ln((Acceptor Concentration*Donor Concentration)/(Intrinsic Electron Concentration^2)) to calculate the Built-in Potential, The Built-in potential formula is defined as the built-in potential in a semiconductor which equals the potential across the depletion region in thermal equilibrium. It also equals the sum of the bulk potentials of each region, since the bulk potential quantifies the distance between the fermi energy and the intrinsic energy. Built-in Potential is denoted by ψ_{o} symbol.
How to calculate Built-in Potential using this online calculator? To use this online calculator for Built-in Potential, enter Thermal Voltage (V_{t}), Acceptor Concentration (N_{a}), Donor Concentration (N_{d}) & Intrinsic Electron Concentration (n_{i}) and hit the calculate button. Here is how the Built-in Potential calculation can be explained with given input values -> 18.81808 = 0.55*ln((1100*190000000000000)/(17^2)).
