Abstract: Compression-induced phase transitions in supercooled liquid and glassy confined germanene are studied via molecular dynamics (MD) simulations. Glassy state is obtained by cooling from the melt to 300 K under zero pressure. Then, some selected atomic configurations at temperatures above and below T g are taken as initial supercooled liquid or glassy two-dimensional (2D) models for the isothermal compression from low-density to high-density states in order to study compression-induced phase transitions in the models. We find formation of the triangular-hexa (trh) germanene as the most stable state in the high-density region. Moreover, we find the compression-induced amorphization of supercooled liquid and amorphous-amorphous phase transitions in the system. [ABSTRACT FROM AUTHOR]
