AI Article Synopsis
- - Germanane (GeH) is a 2D material that's gaining attention for its potential use in electronics, solar cells, and photocatalysis due to its impressive properties.
- - Traditional methods to synthesize GeH are slow, taking 6 to 14 days, but a new technique allows for room temperature synthesis in just a few minutes, making it much more practical for use.
- - The new synthesis method produces highly pure GeH with a band gap of about 1.4 eV, which is an improvement for applications like solar energy conversion.
Article Abstract
Germanane (GeH), a germanium analogue of graphane, has recently attracted considerable interest because its remarkable combination of properties makes it an extremely suitable candidate to be used as 2D material for field effect devices, photovoltaics, and photocatalysis. Up to now, the synthesis of GeH has been conducted by substituting Ca by H in a β-CaGe layered Zintl phase through topochemical deintercalation in aqueous HCl. This reaction is generally slow and takes place over 6 to 14 days. The new and facile protocol presented here allows to synthesize GeH at room temperature in a significantly shorter time (a few minutes), which renders this method highly attractive for technological applications. The GeH produced with this method is highly pure and has a band gap (E ) close to 1.4 eV, a lower value than that reported for germanane synthesized using HCl, which is promising for incorporation of GeH in solar cells.
