“…Because of these properties, there is intense interest in identifying alternative 2-D materials. Recently eight new materials have been identified that have a structure similar to graphene [100]: antimonene [339,340,341], arsenene (a single-layer buckled honeycomb structure of arsenic) [342,343], bismuthine [344], borophane [345,346], borophene [347], phagraphene [348], phosphorene [349] and stanene [350,351,352]. Other similar 2-D materials such as Cr2ge2te6 [353], Rhenim Disulfide [354], Titanium Carbides [355] and Molybdenum ditelluride [356] have unique optical, ferromagnetic, physical or electrical properties.…”
