Attosecond band-gap dynamics in silicon | Science
The band structure of crystalline silicon accommodates both direct and indirect excitations of electrons across the band gap (). At low intensities, a near-infrared (NIR) pump pulse can in principle promote electrons from the VB maximum across the indirect band gap ( E gap = 1.2 eV), satisfying momentum conservation by the addition of a phonon.

Band gap - Simple English Wikipedia, the free encyclopedia
A band gap, also called a bandgap or energy gap, is an energy range in a solid where no electron states can exist. The term is used in solid-state physics and chemistry.Band gaps can be found in insulators and semiconductors.In graphs of the electronic band structure of solids, the band gap is the energy difference (in electron volts) between the top of the valence band and the bottom of the

Is Graphitic Silicon Carbide (Silagraphene) Stable? | …
Graphene is considered to be the most likely candidate for the postsilicon era; however, the problem with its zero band gap is challenging to overcome. A close relative of silicon, silicon carbide is expected to have a stable 2D polymorph which happens to be a wide-gap semiconductor. Unfortunately, the so-called silagraphene has proven to be elusive. To date, neither theoretical nor

Abstract Using the linear augmented cylindrical wave method in the muffin-tin approximation, we have calculated the band structure of (n, n) and (n, 0) silicon carbide nanotubes for n = 5–10.In the range n = 7–10, (n, n) nanotubes are semiconductors, and their band gap decreases steadily with increasing n: 0.28 eV at n = 7, 0.26 eV at n = 8, 0.19 eV at n = 9, and 0.11 eV at n = 10.
