The junctions which formed where n-type and p-type semiconductors are joined together is called pn junction. A diode is a semiconductor device that does not permit current flow when the voltage drop across it is below a certain threshold (different diodes have different characteristics, but we'll consider one hypothetical example). More importantly, semiconductor devices lend themselves to integration into complex but readily build-up microelectronic circuits. Each transistor has its own switch that can be turned on or off individually. The following are the types of transistors: PNP, NPN, JFET, and MOSFET.
