Using a groundbreaking new technique, researchers has revealed previously unrecognized properties of technologically crucial silicon crystals and uncovered new information about an important ...

Silicon is a semiconductor in group IVA of the periodic table with atomic number 14, an atomic weight of 28.086, and a density of 2.33 Mg/m 3. It melts at 1410 C. The electronic configuration of the ...

Metals form crystal lattices similar to silicon, but they are much better conductors because they don’t use up all of their valence electrons in the bonds of the lattice.

Biaxial distortion of the crystal lattice changes the electronic band structure of the silicon whereby electron and hole mobility improves by up to 50%.

As electronic devices shrink, the interaction between electrons and the silicon crystal lattice, described in terms of 'quasiparticles', is a central issue. Ultrashort laser pulses can track the ...

Many semiconductors are based on silicon, with atoms of other elements (such as phosphorus or boron, which are themselves semiconductors) interspersed throughout the silicon crystal lattice in a ...

Even better, the influence of the silicon lattice, which is so disastrous for coupling, acts to break up the energetic states into a series that seem to have very good properties for a qubit.

But silicon has a fatal flaw when it comes to being used as a light source or solar cell. The semiconductor has an “indirect” electronic band gap, which means that electronic transitions between the ...

Where crystalline silicon cells use dopant ions to facilitate electron handoffs between layers of positive and negative charge, perovskites' own crystal lattice alternates between anions and cations.

In a previous color, we’ve talked about what makes things colored — the way objects absorb, reflect, or transmit light at different wavelengths. But let’s be a bit more specific. What gives gemstones ...

One application of shaped wafers is as well-shaped concave silicon crystal lenses or mirrors. The lattice plane of such a crystal lens has a curvature exactly along the surface.

Afterwards, the lattice, composed of the individual atoms in the crystal, rearranges in response to this redistribution of electrons, turning part of the absorbed energy into heat carried by ...
