Large crystal growth, physical properties, and doping studies of SnSe2

Two dimensional (2D) layered metal dichalcogenides, exhibiting diverse physical properties in charge-density-wave (CDW), superconductivity (SC), topology, and thermoelectrics, are attracting great attention in the past few years. In this presentation, we will primarily focus on CdI$_{\mathrm{2}}$-type SnSe$_{\mathrm{2.\thinspace }}$We have successfully grown high quality large size single crystals up to several centimeters using modified Bridgman technique, and carried out systematical doping studies on the SnSe$_{\mathrm{2}}$ crystal through chemical interactions. The resulting physical properties of the grown crystals and intercalated samples will be presented. The potential high thermoelectric properties and superconductivity will also be discussed.
