Source Data used for the manuscript "Experimental realization of the topologically nontrivial phase in monolayer Si2Te2 published in Nature Communications.
Description
In this study we realized the epitaxial growth of strain-free monolayer Si2Te2 on HfTe2 substrate. Scanning tunneling microscopy and spectroscopy reveal an intact (1×1) lattice and a bulk band gap of ~300 meV, consistent with first-principles calculations.
Moreover, pronounced edge states extending ~2.0 nm from the island boundary are observed in monolayer Si2Te2, exhibiting characteristics expected for topological edge modes. Our results establish monolayer Si2Te2 as a large-gap two-dimensional topological-insulator platform for topological phenomena and device concepts at elevated temperatures.
