  • Hydrogen detector based on GaN nanocones 
    POPA, V.; VOLCIUC, O.; SONTEA, V.; TIGINYANU, I. M. (Technical University of Moldova, 2005)
    In this paper, we demonstrate that using GaN nanocone morphology obtained by photo electrochemical etching, it is possible to obtain very stable and easy in manufacturing gas sensors, in particular for hydrogen detection.
  • Mechanisms of enhancement of nonlinear optical response in nanostructured III-V compounds 
    SERGENTU, V.; KRAVETSKY, I.; URSAKI, V.; SIRBU, L.; VOLCIUC, O.; POPA, V.; TIGINYANU, I. M.; BOYD, Robert W. (Technical University of Moldova, 2005)
    The goal of this paper is to propose a new mechanism of nonlinear optical properties enhancement in nanostructured semiconductors based on the concept of photonic crystals (PC). The photonic crystal is usually formed as a ...
