  • ENHANCED RESPONSIVITY OF ZnSe-BASEDMETAL–SEMICONDUCTOR–METAL NEAR-ULTRAVIOLETPHOTODETECTOR VIA IMPACT IONIZATION 
    Sirkeli, Vadim; Yilmazoglu, Oktay; Hajo, Ahid S.; Nedeoglo, Natalia; Nedeoglo, Dmitrii; Preu, Sascha; Küppers, Franko; Hartnagel, Hans (Willey, 2018)
    We report on high‐responsivity, fast near‐ultraviolet photodetectors based on bulk ZnSe employing a metal–semiconductor–metal structure with and without interdigital contacts. A very high responsivity of 2.42 and 4.44 A W−1 ...
  • RECENT ADVANCES IN ZnSe-BASED DEVICES: FROM UV TO TERAHERTZ APPLICATIONS 
    Sirkeli, Vadim P.; Nedeoglo, Natalia D; Nedeoglo, Dmitrii D.; Vatavu, Sergiu A.; Yilmazoglu, Oktay; Hajo, Ahid S.; Preu, Sascha; Hartnagel, Hans L.; Küppers, Franko (CEP USM, 2024)
    Zinc selenide is a II-VI compound material with wide bandgap. Due to its unique properties like direct wide bandgap, high resistance to intense UV and X-Ray radiation, ZnSe is attractive material for fabrication of ...
