  • Flexible pressure sensor based on graphene aerogel microstructures functionalized with CdS nanocrystalline thin film 
    PLESCO, Irina; DRAGOMAN, Mircea; STROBEL, Julian; GHIMPU, Lidia; SCHÜTT, Fabian; DINESCU, Adrian; URSAKI, Veaceslav; KIENLE, Lorenz; ADELUNG, Rainer; TIGINYANU, Ion (ELSEVIER, 2018)
    In this paper, we report on functionalization of graphene aerogel with a CdS thin film deposited by magnetron sputtering and on the development of flexible pressure sensors based on ultra-lightweight CdS-aerogel nanocomposite. ...
  • GaN nanomembranes as memristors with self-rectification 
    DRAGOMAN, Mircea; CIOBANU, Vladimir; DRAGOMAN, Daniela; DINESCU, Adrian; BRANISTE, Tudor; TIGINYANU, Ion (Institute of Nanocience and Nanotechnology, INN, 2017)
    We have recently shown that GaN ultrathin membranes suspended on GaN nanowires having a thickness of 15 nm and planar dimensions of 12×184 microns are acting as memristive devices. The physical effect which explains this ...
  • Learning mechanisms in memristor networks based on GaN nanomembranes 
    DRAGOMAN, Mircea; TIGINYANU, Ion; DRAGOMAN, Daniela; DINESCU, Adrian; BRANISTE, Tudor; CIOBANU, Vladimir (AIP Publishing LLC, 2018)
    We demonstrate experimentally that single crystalline GaN nanomembranes arranged in simple networks exhibit learning mechanisms such as habituation and dishabituation followed by storage of the response to a certain ...
  • Sensing up to 40atm Using Pressure-Sensitive Aero-GaN 
    DRAGOMAN, Mircea; CIOBANU, Vladimir; SHREE, Sindu; DRAGOMAN, Daniela; BRANISTE, Tudor; RAEVSCHI, Simion; DINESCU, Adrian; SARUA, Andrei; MISHRA, Yogendra K.; PUGNO, Nicola; ADELUNG, Rainer; TIGINYANU, Ion (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2019)
    This work reports on the fabrication and characterization of a robust pressure sensor based on aero-GaN. The ultraporous aeromaterial consists of GaN interconnected hollow micro-tetrapods with the wall thickness of about ...
  • A SnS2-based photomemristor driven by sun 
    DRAGOMAN, Mircea; BATIRI, Mihail; DINESCU, Adrian; CIOBANU, Vladimir; RUSU, Emil; DRAGOMAN, Daniela; TIGINYANU, Ion (AIP Publishing LLC, 2018)
    We demonstrate experimentally that a sample of a SnS2 layered semiconductor compound with the area of 1 cm2 and the thickness of 100 μm, contacted laterally by silver electrodes with the area of 1 mm2, acts naturally as a ...
  • Ultra-lightweight pressure sensor based on graphene aerogel decorated with piezoelectric nanocrystalline films 
    DRAGOMAN, Mircea; GHIMPU, Lidia; OBREJA, Cosmin; DINESCU, Adrian; PLESCO, Irina; DRAGOMAN, Daniela; BRANISTE, Tudor; TIGINYANU, Ion (IOP Publishing, 2016)
    In this paper, we report on a pressure sensor based on graphene aerogel functionalized with SnO2 or GaN thin films deposited by magnetron sputtering. Decoration by nanocrystalline SnO2 or GaN was found to enhance the ...
