Put simply, they are made up of germanium atoms. The solid form is grayish in color.
Germanium element has an interesting property. It is one of the metalloids. This means sometimes it can behave or react like a metal or it can also react as a non-metal. It has dual properties which has many uses. They are used in semiconductors and are components in some superconductors.

Germanium is employed as an antireflective coating material for use in active area lithography and gate area lithography steps in the formation of a semiconductor integrated circuit. A germanium layer is deposited over an active area nitride layer or over a gate area nitride layer, and a photoresist layer is then formed on the germanium layer. The photoresist layer is than exposed and developed. During exposure, the germanium layer substantially reduces reflection from the underlying nitride layer, thereby relieving the dependency of exposure energy and resulting line width on the underlying nitride layer thickness. Germanium-silicon may also be employed as the antireflective layer.

germanium-arsinide mixture are used to make some solid state lasers too.
