Few binary compounds attract as much attention as Bi2Se3. In addition to its use as thermoelectric, it has become one of the prototype 3D topological insulators, and it has been demonstrated that doping in appropriate levels can induce magnetism and

Solution processed thin chalcogenide films have attracted noteworthy attention due to the simplicity and thus low cost of applicable deposition techniques (e.g. spin-coating). In presented work we demonstrate the possibility to modify the thin films

In this work, the chalcogenide glass thin films of As-Ge-Sb-S system were prepared in specular optical quality by spin-coating from mixtures of separate As40S60 and Ge20Sb5S75 glass solutions. The five compositions were studied in total (0, 25, 50, 7
