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 ...
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 ...
