Hi every one,
I face with a question on my works,
As you know there in many articles Physicist introduce a material that has zero gap without spin-orbit coupling (SOC). By applying the SOC, a relatively small gap (0.1 eV) is opened and it becomes topological insulator.
My question,
Is that possible to have a material that has a large band gap (1 eV) without SOC and it becomes topological insulator with large gap by applying SOC?
Thanks for your answers,
