What is an UJT?

The UJT or uni junction transistor is a semiconductor device that has only one junction. The UJT has three terminals designated B1, B2 and E. The base material for a UJT is a lightly doped N-Type Silicon bar with ohmic contacts given at the lengthwise ends. These end terminals are called B1 and B2. Since the silicon bar is lightly doped, the resistance between B1 and B2 is very high (typically 5 to 10 KΩ). A heavily doped P-type region is constructed on one side of the bar close to the B2 region. This heavily doped P region is called emitter and it is designated as E. Resistance between E & B1 is higher than the resistance between E & B2 because E is constructed close to B2.
