Chemical Control of Electronic Structure and Topology in Tellurium-Encapsulated Silicene
Gabriel Elyas Gama Araujo, Andre Luis de Oliveira Batista, Willian Oliveira Santos +3
We investigate chemical control of the electronic, optical, and topological properties of two-dimensional \ce{Si2X2Te2} (\ce{X} = \ce{B}, \ce{Al}, \ce{Ga}, and \ce{In}) monolayers…
