The junction creates a barrier that controls the flow of electrons and holes, enabling the creation of diodes, transistors, solar cells, and other essential electronic components. Schematic Diagram of ...

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 threshold, or knee, voltage riseshigher as the LED wavelength becomesshorter. All PN-junction diodes, includingLEDs, have capacitance due to depletionand diffusion profiles. You can light an LED ...
