Web21 de mar. de 2024 · Hint: There are two types of current through a semiconducting material – one is drift current and the other is diffusion current. The mechanism of drift current is similar to the flow of charge in a conductor. In semiconducting material, when a heavy concentration of carrier is introduced to some region, the heavy concentrations of … http://www.ittc.ku.edu/~jstiles/312/handouts/The%20pn%20Junction%20Diode.pdf

The built in potential ( or barrier potential ) for pn junctions is given by following relation, Vbi = Vt ln (Na*Nd/ni²) which is normally of the order of 0.6V to 0.8 V. It can be seen that Vbi is purely function of Temperature and Doping and independent of the external bias.
