Surface alloy engineering in 2D trigonal lattice: giant Rashba spin splitting and two large topological gaps
We demonstrate that sp ^2 based trigonal lattice can exhibit giant Rashba splitting and two large topological gaps simultaneously. First, an effective tight binding model is developed to describe the Rashba spin–orbit coupling (SOC) on a real surface and give a topological phase diagram based on two...
