A tight-binding investigation of biaxial strain induced topological phase transition in GeCH${}_3$

Mohsen Rezaei, Esmaeil Taghizadeh Sisakht, Farhad Fazileh +2

We propose a tight-binding (TB) model, that includes spin-orbit coupling (SOC), to describe the electronic properties of methyl-substituted germanane (GeCH${}_3$). This model gives a…
