Abstract
We perform a detailed analysis of the quantitative structural parameters and energy dissipation channels in a hexagonal phosphorene nanoribbon subjected to shock loading. This external influence leads to the excitation of a compression solitons in the material. We found that to excite shock waves, it is sufficient to apply a directed initial pulse per atomic row in the direction normal to this row. At the same time, these initial conditions do not correspond to the stable profile of the shock wave, and it is formed after a sufficiently short transition period of 0.1 - 0.2 ps. We show that the compression solitons in phosphorene can propagate only in two crystallographic directions, namely in zigzag or armchair. In all cases, shock waves propagate faster than the speed of sound with a sufficiently large energy dissipation. The mechanisms of compression soliton propagation and energy dissipation channels are also investigated in detail.
