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 ...

What does PN junction actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

However, a graphene PN junction has no band gap voltage, so it should be ideal. However, previous attempts to find negative refraction in graphene were not successful.

Using the electric field of a scanning tunnelling microscope (STM), scientists in the US, Europe and Japan have created nanoscale circular p-n junctions in graphene. By controlling the voltage between ...

What is a P-N Junction? A p-n junction is a fundamental building block of modern electronics, formed by joining together two types of semiconductor materials: p-type (positive) and n-type (negative).
