MOISSANITE (Silicon Carbide)

Moissanite is a mineral that was first discovered in fragments of the meteorite at Diablo Canyon or Meteor Crater in Arizona. It was named in honor of its discoverer, Nobel Prize winner Dr. Ferdinand Henri Moissan. Synthetic moissanite is also known as silicon carbide after its chemistry and by the trade name, carborundum..

Using Solar Energy to Create Renewable Fuel

The beauty of coined graphene/cubic silicon carbide is that it creates a graphene-based photoelectrode — an electrode that can absorb light and then kick start an electrochemical transformation. The graphene can function as both a protective layer and a transparent conductor, allowing the cubic silicon carbide to get on with its role of collecting solar energy.

Amorphous_silicon

Amorphous silicon (a-Si) is the non-crystalline allotropic form of silicon. Silicon is a four-fold coordinated atom that is normally tetrahedrally bonded to four neighboring silicon atoms. In crystalline silicon this tetrahedral structure is continued over a large range, forming a well-ordered lattice (crystal).
