  • Chalcogenide materials for emerging memories 
    VELEA, A. (Tehnica UTM, 2019)
    Emerging resistive switching (RS) non-volatile memory (NVM) technologies, such as resistive random access memory (RRAM) or phase change memory (PCM), are promising candidates for the next generation of advanced data storage ...
  • Chalcogenide materials screening for Ovonic Threshold Switching 
    MIHAI, C.; VELEA, A. (Tehnica UTM, 2019)
    The world need for data storage and processing is increasing at a rapid pace. A response to this societal demand could come from ovonic threshold switches based on chalcogenide materials, which are leading candidates for ...
  • Characterization of CZTS thin films obtained by magnetron codeposition from binary sputtering targets 
    DIAGNE, O.; GALCA, A.-C.; SAVA, F.; SIMANDAN, I.-D.; VELEA, A. (Tehnica UTM, 2019)
    If photovoltaic energy is a so-called "clean" energy, the materials used, partly rare or nondurable ores, and the production processes are less so. To overcome the rare, toxic or expensive components of solar panels, ...
  • Nonvolatile resistance switching in monolayer transition metal dichalcogenides: an explanation 
    SAVA, F.; VELEA, A.; MIHAI, C. O.; BURUIANA, A. T. (Tehnica UTM, 2019)
    Recently, Ge et. al. [1] showed that in atomic sheets of transition metal (from the group VI B) dichalcogenides (TMD) (Fig. 1) (MoS2, MoSe2, WS2 and WSe2) nonvolatile resistance switching occurs. In order to understand ...
  • Optical properties of binary and ternary chalcogenides 
    GALCA, A.-C.; SAVA, F.; SIMANDAN, I.-D.; SOCOL, G.; VELEA, A. (Tehnica UTM, 2019)
    Development of memories based on novel chalcogenide materials are among the research directions of many research units aiming discovery of new or improved optical or electric storage media.
  • Structural and optical properties of amorphous GeTe films 
    SIMANDAN, I. D.; GALCA, A. C.; SAVA, F.; BUCUR, C.; DUMITRU, V.; POROSNICU, C.; MIHAI, C.; VELEA, A. (Tehnica UTM, 2019)
    Chalcogenide amorphous materials are known to have different structural and optical properties depending on the deposition method. Here, we investigate thin amorphous GeTe films [1] obtained through co-sputtering from ...
