      Electron microscopy study of thermoelectric (BixSb1-x)2Te3thin film 

      Breza, A.; Lioutas, C. B.; Giapintzakis, John (Springer Science and Business Media, LLC, 2015)
      In the present work, transmission electron microscopy (TEM) techniques were used in order to study the morphology and investigate the structural properties of a (BixSb1-x)2Te3(BST) thin film. The sample was fabricated on ...

      Memristive and neuromorphic behavior in a Li x CoO 2 nanobattery 

      Mai, V. H.; Moradpour, A.; Senzier, P. A.; Pasquier, C.; Wang, K.; Rozenberg, M. J.; Giapintzakis, John; Mihailescu, C. N.; Orfanidou, C. M.; Svoukis, E.; Breza, A.; Lioutas, C. B.; Franger, S.; Revcolevschi, A.; Maroutian, T.; Lecoeur, P.; Aubert, P.; Agnus, G.; Salot, R.; Albouy, P. A.; Weil, R.; Alamarguy, D.; March, K.; Jomard, F.; Chrétien, P.; Schneegans, O. (2015)
      The phenomenon of resistive switching (RS), which was initially linked to non-volatile resistive memory applications, has recently also been associated with the concept of memristors, whose adjustable multilevel resistance ...

      Nanostructure and doping stimulated phase separation in high-ZT Mg2Si0.55Sn0.4Ge0.05 compounds 

      Polymeris, G. S.; Vlachos, N.; Khan, A. U.; Hatzikraniotis, E.; Lioutas, C. B.; Delimitis, A.; Pavlidou, E.; Paraskevopoulos, K. M.; Kyratsi, Theodora (2015)
      A study was attempted on the structural properties across all relevant length-scales for Mg2(Si,Sn,Ge)-type solid solutions of the formula Mg2Si0.55- ySn0.40Ge0.05(Bi,Sb)y. The study focuses on three families of samples, ...

      Structural features of ball-milled nanostructured K2Bi 8Se13 thermoelectric material 

      Lioutas, C. B.; Hatzikraniotis, E.; Ioannou, M.; Paraskevopoulos, K. M.; Kyratsi, Theodora (2011)
      In this work, K2Bi8Se13 material was ball-milled in order to develop nanostructures through the modification of structural features. Structural changes during ball-milling were followed by powder X-ray diffraction measurements, ...
