Abstract

This research project is about the growth of high-quality single crystals by the self-flow method and by the vapor method of dichalcogenides that crystallize in the CdI2 prototype. Preliminary results shown in this plan suggest that it is possible to grow high-quality crystals by these methods represented by a member of the family which is Ni0.02ZrTe2. Boundary structure calculations, as well as some results reported in the literature, show that this type of prototype presents a non-trivial topology and, in this sense, the superconductivity from this prototype can be a clear example of non-artificial topological superconductors. In addition to these aspects relevant to Condensed Matter Physics, the plan presented below is intended to foster Ph.D., Master's and Scientific undergraduate students who are currently working in our Lorena Research Group at EEL-USP.
