Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by ...

When light interacts with metallic nanostructures, it instantaneously generates plasmonic hot carriers, which serve as key ...

As demand for next-generation semiconductor chips grows, a team of researchers has succeeded in laser-drilling the world's tiniest circuit board holes, measuring a near-inconceivable 3 micrometers ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon ... to form the bonds with the surrounding silicon atoms, an electron vacancy or “hole” is created. The n-type ...

Luckily, a semiconductor is perfectly suited to this job. It is exquisitely sensitive to how many extra or missing electrons are inside. Each time the input signal shoves more holes into the ...

In particular, electrons flow better than holes through the material ... According to researchers, this material is a superior semiconductor and, possibly, the best possible semiconductor.

The answer is that it makes use of a photonic crystal — a semiconductor layer patterned with a custom-designed periodic array of specially-shaped small air holes (nanometre scale). This ...

Fixed donor atoms contribute the electrons and holes in the n- or p-type semiconductors, so both sides of the device are electrically neutral far from the interface. The electrons and holes want ...
