Ambiguous Role of Growth-Induced Defects on the Semiconductor-to-Metal Characteristics in Epitaxial VO2/TiO2 Thin Films
Mihailescu, Cristian N.; Symeou, Elli; Svoukis, Efthymios; Negrea, Raluca F.; Ghica, Corneliu; Teodorescu, Valentin; Tanase, Liviu C.; Negrila, Catalin; Giapintzakis, John (2018)Controlling the semiconductor-to-metal transition temperature in epitaxial VO2 thin films remains an unresolved question both at the fundamental as well as the application level. Within the scope of this work, the effects ...

Low Temperature Synthesis as a Route for Highly Thermoelectric Efficient Na-Doped PbTe
Papageorgiou, Chryssi; Delimitis, Andreas; Symeou, Elli; Giapintzakis, Ioannis; Kyratsi, Theodora (2018)In this work, Na-doped PbTe is synthesized through a low temperature synthesis technique. This method provides highly efficient p-type PbTe using a synthesis temperature much lower than the PbTe melting point and as low ...
