Schematic Diagram of a P-N Junction Diode: The diagram illustrates the basic structure of a p-n junction diode with p-type silicon on one side, n-type silicon on the other, and the anode and cathode ...

The PN junction is one of the primary building blocks of semiconductors. Diodes and Thyristors A diode (one way valve) is a PN junction with p-type on one side and n-type on the other.

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. Continue reading → ...

The PN junction formed inside the wafer is illuminated with a femtosecond laser (an ultrashort pulse laser), and the terahertz electromagnetic waves (THz waves) are successfully measured due to ...

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 ...
