General description

Germanane (GeH) is a 2D graphane analog with a direct band gap of 1.6 eV and electron mobility of 18000 cm2V-1s-1. It is a hydrogen terminated germanium (Ge) which can be synthesized by the topotactic deintercalation of CaGe2 crystals. Its crystal structure contains hexagonal Ge lattice with hydrogen atoms that are covalently attached to every Ge atom.

Application

GeH is a van der Waals material that can be used in a variety of applications such as electronic, optoelectronic, sensing and energy conversion.

Graphene's success has shown not only that it is possible to create stable, single-atom-thick sheets from a crystalline solid but that these materials have fundamentally different properties than the parent material. We have synthesized for the first time, millimeter-scale crystals
