Abstract

This work plan is about the growth of high quality single crystals by the self-flux method of dicalcogens that crystallize in the CdI2 prototype. Preliminary results shown in this plan strongly suggest that it is possible to grow high quality single crystals by this method represented by a member of the family which is Ni0.02ZrTe2. Band 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 that coming from this prototype can be a clear example of non-artificial topological superconductors. In addition to these aspects relevant to Condensed Matter Physics, the following plan intends to complement the formation of this candidate, in this effervescent area of the new Condensed Matter Physics
