Germanium has been said by many to be a metal, but it is only carrying characteristics of a metal so it can be called a semi-metal. Optical constants of the noble metals, Phys. Silicon is a metalloid. Metallurgical Grade Silicon (MG-Si) MG-Si is the result of purifying silicon using heat and reducing agent. Seperti germanium, silikon agak kuat tetapi sangat rapuh dan mudah mengelupas. Graphite displays both metallic and non-metallic properties making it appropriate for some modern applications. Tungsten carbide (WC) is probably the most widely encountered covalent solid, owing to its use in carbide cutting tools and as the material used to make the rotating balls in ball-point pens. References. 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. However, provided the concentration of SiO 2 is kept high, the silicon carbide can be eliminated: 2 SiC + SiO 2 → 3 Si + 2 CO.

A band gap, also called a bandgap or energy gap, is an energy range in a solid where no electron states can exist. Silicon crystallizes in the same pattern as diamond, in a structure which Ashcroft and Mermin call "two interpenetrating face-centered cubic" primitive lattices.The lines between silicon atoms in the lattice illustration indicate nearest-neighbor bonds. Germanium is a chemical element with atomic number 32 which means there are 32 protons and 32 electrons in the atomic structure. In the case of germanium and silicon, the isolated disordered regions anneal at moderate temperatures of approximately 200° and 300° C, respectively.The amorphous layers also anneal in a characteristic fashion, but at appreciably higher temperatures, i.e., at approximately 600° C in silicon … Isolated disordered regions and the amorphous layer have widely different anneal behavior represents the percent germanium carbide wiki of are!
