This Demonstration considers the atomic structure of singlelayer 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 singlelayer dots.
Multilayer phosphorene structures generated by the algorithm presented in this Demonstration have been studied in [1]. The singlelayer 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 twodimensional, materialbased quantum dots such as silicene or graphene [4, 5]. [1] H. Abdelsalam, V. A. Saroka, I. Lukyanchuk and M. E.
