Phosphorene Quantum Dots

This Demonstration considers the atomic structure of single-layer and multilayer phosphorene quantum dots. It explores their shapes, crystallographic orientations and edge termination. You can generate irregular edge terminations modeled by random fractals for single-layer dots.

Multilayer phosphorene structures generated by the algorithm presented in this Demonstration have been studied in [1]. The single-layer structures including those with the random fractal edges modeling of the edge disorder have been studied in [2]. The model should be especially useful for quantum chemistry studies similar to [3]. The model presented here can be also useful for other two-dimensional, material-based quantum dots such as silicene or graphene [4, 5].
