Germanane

<p>Germanane is a single-layer crystal composed of <a href="/facts/Germanium/wtoALHGs">germanium</a> with one <a href="/facts/Hydrogen/BoYHjl0J">hydrogen</a> bonded in the z-direction for each atom, in contrast to <a href="/facts/Germanene/kDY7Jb1d">germanene</a> which contains no hydrogen. In <a href="/facts/Material_science/N5HrXRYW">material science</a>, great interest is shown in related single layered materials, such as <a href="/facts/Graphene/QDGUBaPt">graphene</a>, composed of carbon, and silicene, composed of <a href="/facts/Silicon/cgWx0hdr">silicon</a>. Such materials represent a new generation of semiconductors with potential applications in <a href="/facts/Computer_chip/fjn6vg7C">computer chips</a> and <a href="/facts/Solar_cells/3L814UCC">solar cells</a>. Germanane's structure is similar to <a href="/facts/Graphane/3QMVg24s">graphane</a>, and therefore graphene.  Bulk germanium does not adopt this structure.  Germanane has been produced in a two-step route starting with calcium germanide. From this material, the calcium is removed by de-intercalation with HCl to give a layered solid with the empirical formula GeH. The Ca sites in <a href="/facts/Zintl_phase/RdV0yDXf">Zintl phase</a> CaGe2 interchange with the H atoms in the HCl solution, which leaves GeH and CaCl2.
