Topological phase transition in GeSnH${}_2$ induced by biaxial tensile strain: A tight-binding study

Zahra Aslani, Esmaeil Taghizadeh Sisakht, Farhad Fazileh +2

An effective tight-binding (TB) Hamiltonian for monolayer GeSnH${}_2$ is proposed which has an inversion-asymmetric honeycomb structure. The low-energy band structure of our TB model…
