Abstract

This study presents a detailed analysis of wave processes in the two-dimensional structure of black phosphorene subjected to continuous longitudinal compression. The compression is strictly performed in two crystallographic orientations of phosphorene: either in the "zigzag" direction or in the "armchair" direction. The complex atomic geometry of phosphorene, which differs from the structure of graphene, gives additional complexity to the dynamics of wave propagation occurring due to compression. We employ molecular dynamics methods to simulate the dynamic phenomena. We excite process of acoustic and shock waves using a compressing piston moving at a constant predetermined speed. The study involves a comprehensive analysis of the propagation of the wavefront at the atomic level, which includes the vibrations of atoms passing through the waves and the changes in energy parameters of atoms and waves depending on the piston movement speed. The obtained results contribute to the understanding of nonlinear wave processes in two-dimensional materials, expanding our understanding of wave behavior in complex geometric crystalline structures. This research helps to gain a deeper understanding of the mechanisms of propagation and evolution of shock and acoustic waves in materials such as phosphorene and is of significant importance for the development of novel nanomaterials and technologies. The results obtained extend our understanding of the dynamics of materials at the atomic level and may find practical applications in nanotechnology and the development of new materials with improved properties.
