Here, we demonstrate that the electronic structure can be explained by the effective strain effect due to substrates. More importantly, we find that this electronic structure can be tuned into robust topological phases from a topologically trivial metallic phase by the spin-orbital interaction and couplings to substrates. The topological phase is robust against any perturbations that preserve the time-reversal symmetry. Our study suggests that nontrivial topology and high-T-c superconductivity can be intertwined in the single FeSe layer to search novel physics  ISSN : 2160-3308  Journal Name : PHYSICAL REVIEW X  Volume : 4  Issue Number : 3  Publishing Year : 1435 AH 2014 AD  Article Type : Article  Added Date : Sunday, July 30, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email Ningning Hao Hao, Ningning Researcher     Jiangping Hu, Hu, Jiangping Researcher Doctorate   Files File Name Type Description  42341.pdf pdf   Back To Researches Page
