“…In order to produce smaller devices, thin, stable, durable and electrically tunable materials are required. Although, various nanostructural forms of germanium nitrides, such as nanobelts, have been reported in the sizes of 30 to 300 nm in width both in α-Ge 3 N 4 and β-Ge 3 N 4 phases [41][42][43], its 2D single-layer form has not been investigated to date.…”
