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 ...

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 ...

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 ...
