A dilute distribution of magnetic impurities is assumed to be present in doped graphene. We calculate the interaction energy between two magnetic impurities which are coupled via the indirect-exchange or Ruderman-Kittel-Kasuva-Yosida (RKKY) interaction by the doped conduction elec-trons. The current model is a half- lled AB-lattice structure.

Jul 24, 2019· Ferro-alloys are alloys of iron and other elements such as vanadium, molybdenum or silicon. They are primarily used in the production of carbon and stainless steel to add elements into molten metal during the steelmaking process. Thus, the main demand driver for ferro-alloys is global steel production levels.

Superconductivity in single-crystalline, aluminum- and

for Al doped Ge should be slightly higher than that for Ga doped sample, mainly due to slightly higher phonon-carrier coupling. The T C for Ge:Al is 0.48 K and for the Ge:Ga system the T C should be about 0.43 K. According to our calculation(s) the superconductivity in diluted p-type hyperdoped Ge should be phonon- mediated.

List of semiconductor materials - Wikipedia

A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors typically form in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).

Strategic Materials - dla.mil

A mixture of carbon material (usually petroleum coke) and either silica or quartz sand is reacted at high temperatures (1,700 – 2,500°C) resulting in the formation of α-SiC. Silicon carbide occurs in nature as the extremely rare mineral moissanite Virtually all the silicon carbide sold in the world is synthetic.

GaN Technology - GaN-on-Si - Transphorm

Why GaN-on-Si? Silicon-based power transistors are reaching limits of operating frequency, breakdown voltage and power density in the power electronics industry and GaN’s performance is beginning to shine. By no means is silicon going extinct, but energy requirements are continuing to increase, thereby requiring new methods and materials to be investigated/used to meet these demands.
