List of semiconductor materials - Wikipedia

Semiconductor materials are nominally small band gap insulators.The defining property of a semiconductor material is that it can be doped with impurities that alter its electronic properties in a controllable way.. Because of their appliion in the computer and photovoltaic industry—in devices such as transistors, lasers, and solar cells—the search for new semiconductor materials and the

3.1.6.2 Schottky Contact - TU Wien

3. 1. 6. 2 Schottky Contact A Schottky barrier refers to a metal-semiconductor contact having a large barrier height (i.e. and low doping concentration that is less than the density of states in the conduction band or valence band. The potential barrier between the metal and the semiconductor can be identified on an energy band diagram.

Ultrafine spherulite Mg alloy with high yield strength

May 05, 2019· W in Table 1 means Mg 3 Zn 3 Y 2 intermetalic compound phase with cubic lattice. On the other hand, M12 exhibited a higher σ 0.2 than Mg alloys and Mg 2 Zn(SiC) composites . The difference of mechanical properties between M12 and M9 could be explained by the polycrystalline solidifiion structures (lamella and spherulites) of these materials.
