Strain-induced phase transitions and high carrier mobility in two-dimensional Janus MGeSN2 (M = Ti, Zr, and Hf) structures: First-principles calculations

In this study, we construct new 2D Janus $M$GeSN$_2$ ($M=$ Ti, Zr, and Hf) monolayers and systematically investigate their electronic band structures under applied biaxial strain. The crystal lattice, electronic...
