2D layered materials have emerged in recent years as a new platform to host novel electronic, optical, or excitonic physics and develop unprecedented nanoelectronic energy applications. By definition, these are strongly anisotropic between the basal plane cross plane. The structural property anisotropies inside their plane, however, much less investigated. Black phosphorus, for example, is material that has such in-plane anisotropy. Here, rare chemical form of arsenic, called black-arsenic...
