1Band gap — This article is about solid state physics. For voltage control circuitry in electronics, see Bandgap voltage reference. In solid state physics, a band gap, also called an energy gap or bandgap, is an energy range in a solid where no electron… …
2Direct and indirect band gaps — In semiconductor physics, the band gap of a semiconductor is always one of two types, a direct band gap or an indirect band gap. The band gap is called direct if the momentum of electrons and holes is the same in both the conduction band and the… …
3spectroscopy — spectroscopist /spek tros keuh pist/, n. /spek tros keuh pee, spek treuh skoh pee/, n. the science that deals with the use of the spectroscope and with spectrum analysis. [1865 70; SPECTRO + SCOPY] * * * Branch of analysis devoted to identifying… …
4Optical fiber — A bundle of optical fibers A TOSLINK fiber optic audio c …
5Optical amplifier — An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from… …
6Mercury cadmium telluride — HgCdTe or mercury cadmium telluride (also cadmium mercury telluride, MCT or CMT) is an alloy of CdTe and HgTe and is sometimes claimed to be the third semiconductor of technological importance after silicon and gallium(III) arsenide. The amount… …
7Solid-state physics — Solid state physics, the largest branch of condensed matter physics, is the study of rigid matter, or solids. The bulk of solid state physics theory and research is focused on crystals, largely because the periodicity of atoms in a crystal mdash; …
8DPPH — IUPAC name di(phenyl) (2,4,6 trinitrophenyl)iminoazanium …
9Keating Model — The Keating Model is a model introduced by P. N. Keating in 1966 for the forces induced on neighboring atoms when one atom is moved in a solid. It is most often applied to the forces on first and second nearest neighboring atoms which arise when… …
10Crystallographic defects in diamond — Synthetic diamonds of various colors grown by the high pressure high temperature technique, the diamond size is 2 mm …
