How to Calculate Surface potential?
Surface potential calculator uses surface_potential = 2*Threshold voltage*log10(Acceptor concentration/Intrinsic Concentration) to calculate the surface potential, The Surface potential formula is defined as is a key parameter in evaluating the DC property of thin-film transistors.The externally applied potential is equal to the voltage drop across the oxide layer plus the voltage drop across the semiconductor. surface potential and is denoted by Φs symbol.
How to calculate Surface potential using this online calculator? To use this online calculator for Surface potential, enter Threshold voltage (V_{T}), Acceptor concentration (N_{a}) and Intrinsic Concentration (ni) and hit the calculate button. Here is how the Surface potential calculation can be explained with given input values -> 800 = 2*50*log10(1000000000/10).
