NCERT Class 12 Physics Chapter 14 Semiconductor ... carriers and trivalent atoms are the dopants. 3. In an unbiased p-n junction, holes diffuse from the p-region to the n-region because (a ...

This course presents in-depth discussion and analysis of pn junction and metal-semiconductor contacts including equilibrium behavior, current and capacitance responses under bias, breakdown, ...

The PN junction is one of the primary building blocks of semiconductors. A diode (one way valve) is a PN junction with p-type on one side and n-type on the other. When a positive voltage is ...
