Phosphorene: A 2D New Derivative of Black Phosphorous

Phosphorene is a stable 2D elemental material obtained via the exfoliation of 3D layered phosphorus. Phosphorene exhibits several interesting features, including its unique highly buckled structural characteristics which lead to strong anisotropies in the transport, electronic, optical, mechanical, and thermal properties of this material along its two directions: zigzag and armchair. These excellent properties render phosphorene an ideal platform for various optoelectronic devices. However, under atmospheric conditions, for example, in the presence of oxygen, water, and light, phosphorene is very reactive due to the free non-bonding electrons existing on its surface. Consequently, the O-concentrations effect on the optoelectronic response, the elastic parameters, and thermal conductivity of phosphorene is significant and indicates interesting results.
