      Electrical spin injection and band offsets in an n-type ferromagnetic semiconductor heterostructure: n-CdCr2Se4 / AlGaAs / GaAs 

      Jonker, B. T.; Hanbicki, A. T.; Kioseoglou, G.; Li, C. H.; Stroud, R. M.; Sullivan, J. M.; Erwin, S. C.; Lüpke, G.; Zhao, H. B.; Ren, Y. H.; Sun, B.; Itskos, Grigorios; Mallory, R.; Yasar, M.; Petrou, Athos Chariton (2003)
      The electrical spin injection and band offsets in an n-type ferromagnetic semiconductor heterostructure were discussed. The electrical spin injection from spin-LED structures showed defect-dominated electroluminescence. ...

      Electrical spin injection and band offsets in an n-type ferromagnetic semiconductor heterostructure: n-CdCr2Se4/AlGaAs/GaAs 

      Jonker, B. T.; Hanbicki, A. T.; Kioseoglou, G.; Li, C. H.; Stroud, R. M.; Sullivan, J. M.; Erwin, S. C.; Lüpke, G.; Zhao, H. B.; Ren, Y. H.; Sun, B.; Itskos, Grigorios; Mallory, R.; Yasar, M.; Petrou, Athos Chariton (Institute of Electrical and Electronics Engineers Inc., 2003)
      Electrical spin injection and band offsets in an n-type ferromagnetic semiconductor heterostructure of CdCr2Se4-AlGaAs-GaAs are studied. Epitaxially grown CdCr2Se4 films exhibit hysteresis behavior with significant remanence, ...

      Electroluminescence by a Sm3+-diketonate-phenanthroline complex 

      Stathatos, Elias; Lianos, P.; Evgeniou, E.; Keramidas, Anastasios D. (2003)
      The development of an organic light emitting diode (OLED) based on the use of Sm3+ complex as an emitting layer was investigated. The construction process also involved the use of poly(vinylcarbazole) (PVK) as the transporter ...

      Electroluminescence from a volatile europium complex 

      Stathatos, Elias; Panayiotidou, L.; Lianos, P.; Keramidas, Anastasios D. (2006)
      Three new strongly chelating heterocyclic ligands containing pyridine, imidazole and triazine rings have been used to make ternary complexes of Europium(III) ions together with trifluoroacetylacetonate. The complex containing ...

      Optoelectronic characterization and luminescent coupling effects in multi-junction solar cells 

      Paraskeva, Vasiliki S. (Πανεπιστήμιο Κύπρου, Πολυτεχνική Σχολή / University of Cyprus, Faculty of Engineering, 2017-03)
      Κατά την διάρκεια των περασμένων ετών, τα φωτοβολταϊκά έχουν επιδείξει μια ραγδαία εξέλιξη και ένα ευρύ φάσμα τεχνολογιών έχει αναδυθεί από τους κατασκευαστές. Τα φωτοβολταϊκά πρώτης γενεάς που βασίζονται στην τεχνολογία ...

      Outdoor study of Photovoltaic Mini-Modules with different perovskite compositions 

      Paraskeva, Vasiliki; Hadjipanayi, Maria; Norton, Matthew; Aguirre, Aranzazu; Krishna, Anurag; Ebner, Rita; Fontanot, Tommaso; Pechmann, Sabrina; Christiansen, Silke; Georghiou, George E. (IEEE, 2023)
      A long-term outdoor study of photovoltaic mini-modules with different perovskite compositions was undertaken to detect differences in their long-term performance that could be attributed to their composition. Diurnal ...
