Application

Germanane is novel 2D graphene analog material. However, in sharp contrast to graphene it exhibits semiconducting properties with direct band gap of 1.50 eV. Germanane exhibits high electron mobility and its alkylation allows band gap tuning from 1.50 eV for allyl to 1.62 for methyl germanane. The semiconducting properties of alkylated germanane make them suitable for application is photocatalysis, optoelectronic, sensing etc.

The high theoretical energy density of alloyed lithium and germanium (Li15Ge4), 1384 mAh/g, makes germanium a promising anode material for lithium-ion batteries. However, common alloy anode architectures suffer from long-term instability upon repetitive charge-discharge cycles that arise from stress-induced degradation
