Scientists have unlocked a new understanding of mesoporous silicon, a nanostructured version of the well-known semiconductor.

A silicon atom has four electrons in its outer shell and bonds tightly with four surrounding silicon atoms creating a crystal matrix with eight electrons in the outer shells. However, phosphorus ...

Moreover, silicon-based thermoelectric systems should ... which carry most of the heat, and electrons, which carry the electric current and some of the heat. Thermoelectric performance is usually ...

The n-type silicon is made by including atoms that have one more electron in their outer level than does silicon, such as phosphorus. Phosphorus has five electrons in its outer energy level, not four.

The key point is that electrons can only pass through the dot ... on a substrate in a bottom-up approach, or burning off silicon in the top layer of silicon carbide crystals in a top-down approach.

Using a specially developed etching apparatus, researchers produced mesoporous silicon layers with countless tiny pores and ...

So manufacturers beef up or "dope" the cell's two silicon layers with trace amounts of additives, typically phosphorus and boron. The top, phosphorus-doped layer contains more electrons ...

Today's computers are based on shuttling electrons around in silicon. Electrons in silicon could also form the basis of a completely different breed of computers—quantum computers. Numerous ...

limited amount of electrons running around, high heat could stop a transistor from working altogether. While still working at Bell Labs in 1950, Teal began growing silicon crystals to see if they ...

From computer chips to image sensors in cameras, today's technology is overwhelmingly based on a semiconductor called silicon ...

However, the vast majority of chips are still made from silicon, which is abundant and cheap. The most important advantage of gallium arsenide is speed. Electrons travel about five times faster in ...

They synthesized a series of silicon nanostructures using an etching technique optimized at HZB and determined the temperature-dependent electrical conductivity and thermopower. Electrons in ...
