germanium

en-noun

germanium (countable and uncountable, plural germaniums)

This equipment, which includes transformers, germanium rectifiers and smoothing apparatus, has been designed to allow the existing electric multiple-unit traction motors to operate on rectified alternating current.

1959 March, “Talking of Trains: New B.R. locomotive orders”, in Trains Illustrated, page 118:

The isolated disordered regions and the amorphous layer have widely different anneal behavior. 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 and 400° C in germanium.

germanene

Calculating the complex dielectric function for optical interband transitions we show that the two-dimensional crystals silicene and germanene possess the same low-frequency absorbance as graphene.

We present first-principles studies of the optical absorbance of the group IV honeycomb crystals graphene, silicene, germanene, and tinene.

After the successful synthesis of silicene in 2012, which was followed by a surge of studies on elemental, novel two-dimensional (2D) materials beyond graphene, a daunting quest was to obtain germanene, the germanium-based analogue of graphene, already predicted to possibly exist in 2009.
