First principles calculations of electric field driven topological phase transitions in silicene, germanene and stanene

The emergence of two-dimensional topological materials, particularly the group-14 monolayers known as silicene, germanene, and stanene has opened promising pathways for next-generation nanoelectronics and spintronics. Their buckled honeycomb structure and strong spin–orbit coupling allow for bandgap engineering via a p...
