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).

This video explains what a diode is and how it controls the direction of current in electronic circuits. Diodes allow current ...

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 ...

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 ...

This video explains how LEDs (Light Emitting Diodes) function and why they are widely used in modern lighting and electronic displays. LEDs convert electrical energy into light through the movement of ...

In the past few years, the research effort on 2D materials has rapidly increased, driven by the great variety of layered materials and their exceptional properties when reduced to a few atomic layers ...

In conventional organic solar cells, the electrons exhibit their particle-nature and need to jump between organic molecules in the cell. The conductivity is, therefore, lower than that of crystalline ...

Pennsylvania State University researchers have devised a technique for embedding an electronic junction directly into optical fiber, which potentially paves the way for more streamlined optical ...
