Formed at the boundary between an N-type and P-type semiconductor is a P-N Junction which is created by doping a single crystal of semiconductor. The nature of the P-N junction is one of the crucial ...

For the standard junction diode, there are two operating regions and three possible biasing conditions. There is no external potential energy applied to the P-N junction when a diode is connected in a ...

Physicists in the US are the first to have created a locally-gated p-n junction in graphene, which is a 2D sheet of carbon just one atom thick. The charge density in the device is controlled by ...

The feature size of silicon-based transistors is approaching the theoretical limit, which puts forward higher requirements for the “atomic level manufacturing” of semiconductors. The basic idea of ...
