  • Electron field emission from narrow band gap semiconductors InAs 
    LITOVCHENKO, V.; EVTUKH, A.; SEMENENKO, M.; GRYGORIEV, A.; YILMAZOGLU, O.; HARTNAGEL, H. L.; SIRBU, L.; TIGINYANU, I. M.; URSAKI, V. V. (IOP Publishing, 2007)
    We propose to use InAs for the development of effective electron field emitters on the basis of a new technological approach for the preparation of highly textured surfaces which allows one to obtain peculiar fine rod-like ...
  • Enhanced efficiency of p-GaN/n-ZnO light-emitting diodes by using NiO and ZnSe interlayers 
    SIRKELI, V. P.; YILMAZOGLU, O.; KÜPPERS, F.; HARTNAGEL, H. L. (Technical University of Moldova, 2015)
    We report the results from numerical simulations of p-GaN/n-ZnO light-emitting diodes (LEDs) with different architectures. p-GaN/n-ZnO, p-GaN/p-NiO/n-ZnO, and p-GaN/p-NiO/n-ZnSe/n-ZnO LED structures have been examinated ...
  • Internal quantum efficiency enhancement of InGaN/GaN LEDs with Mg-Si pin-doped GaN quantum barrier 
    KÜPPERS, F.; SIRKELI, V. P.; YILMAZOGLU, O.; AL-DAFFAIE, S.; OPREA, I.; ONG, D. S.; HARTNAGEL, H. L. (Institutul de Fizică Aplicată al AŞM, 2018)
    In this work we study numerically the effect of Mg-Si pindoping of GaN quantum barrier within InGaN/GaN multi quantum wells (MQWs) on the internal quantum efficiency (IQE) of LEDs in comparison with LED devices with undoped, ...
  • Technology of Wide-Bandgap Diode Structures for Highfrequency Operation 
    MUTAMBA, K.; YILMAZOGLU, O.; COJOCARI, O.; SYDLO, C.; PAVLIDIS, D.; HARTNAGEL, H. L. (IEEE, 2006)
    This paper reports on technology development aspects for GaN-based diodes in view of their application at high frequencies. The investigated devices include structures for transferred electron effects for operation at high ...
  • ZnO-based Quantum Structures for Terahertz Sources 
    SIRKELI, V. P.; HARTNAGEL, H. L.; YILMAZOGLU, O.; PREU, S. (Tehnica UTM, 2019)
    In this paper we report on the numerical study of the terahertz devices based on metal oxide semiconductors and its application in biology and medicine. We also report on the recent progress of the theoretical and experimental ...
