Silicon detector Patented and first manufactured in 1906 by Pickard, this was the first type of crystal detector to be commercially produced. Silicon required more pressure than the whisker contact, although not as much as carborundum. A flat piece of silicon was eedded in fusible alloy in a metal cup, and a metal point, usually brass or gold, was pressed against it with a spring.

Tungsten carbide | chemical compound | Britannica
Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600 C (4,700 F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400 –1,600 C (2,550 –2,900 F).
Thermal Synthesis - Graphite Products
In the case of beta silicon carbide, two source materials, one carbon and one silicon bearing, are reacted in the furnace to form a unique form of beta silicon carbide. This high-temperature treatment leads to the formation of cubic beta silicon carbide, which differs from the well-known alpha silicon carbide in certain important aspects.
Bismuthene is a newly developed graphene-like 2D …
The silicon carbide structures causes the bismuth atoms to arrange in a honeyco structure - which reseles the structure of graphene films. The researchers call their new material "bismuthene". Unlike graphene, Bismuthene forms a chemical bond to the substrate, which plays a central role in the new concept to provide the material with the desired electronic properties.
