  • Polarized Retroreflection from Nanoporous III–V Semiconductors 
    PRISLOPSKI, S. Ya.; GAPONENKO, S. V.; MONAICO, E.; SERGENTU, V. V.; TIGINYANU, I. M. (Springer Nature Switzerland, 2018)
    Retroreflected light with strong linear polarization coinciding with that of the incident beams is detected from strongly absorbing nanoporous III–V semiconductors. Because of high polarization of retroreflected waves we ...

    TIGINYANU, I. M.; URSAKI, V. V.; MONAICO, E.; FOCA, E.; FÖLL, H. (The Electrochemical Society, 2007)
    We propose to use a neutral electrolyte based on an aqueous solution of instead of commonly used aggressive acids or alkaline electrolytes for the purpose of electrochemical nanostructuring of and substrates. It is shown ...
  • Porosity-induced blueshift of photoluminescence in CdSe 
    MONAICO, E.; URSAKI, V. V.; TIGINYANU, I. M. (American Institute of Physics, 2006)
    Porous CdSe layers have been fabricated by anodic etching of n-type single crystalline substrates with different values of conductivity. The morphology and porosity of the layers thus produced were found to be controlled ...
  • Porosity-induced gain of luminescence in CdSe 
    MONAICO, E.; URSAKI, V. V.; URBIETA, A.; FERNÁNDEZ, P.; PIQUERAS, J.; BOYD, R. W.; TIGINYANU, I. M. (IOP Publishing, 2004)
    Porous CdSe layers have been produced by anodic etching of crystalline substrates in a HCl solution. Anodization under in situ UV illumination resulted in the formation of uniformly distributed parallel pores with a diameter ...
  • Porous II-VI vs. porous III-V semiconductors 
    LANGA, S.; TIGINYANU, I. M.; MONAICO, E.; FÖLL, H. (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2011)
    In this work a morphological comparison of porous structures obtained by means of electrochemical etching in II-VI (ZnSe, CdSe) and III-V (InP, GaAs, GaP) semiconductors is presented. It is shown that in III-V semiconductors ...

    We report on templated fabrication of metal nanotubes by electrochemical pulsed deposition of Pt in InP and ZnSe porous layers with pore diameters from 40 to 400 nm. Ordered two-dimensional hexagonal arrays of pores are ...
  • Random lasing in nanostructured ZnO produced from bulk ZnSe 
    URSAKI, V. V.; ZALAMAI, V. V.; BURLACU, A.; KLINGSHIRN, C.; MONAICO, E.; TIGINYANU, I. M. (IOP Publishing, 2009)
    We propose to produce three-dimensional ZnO random laser media on the basis of bulk ZnSe. Bulk ZnSe wafers are transformed into granular ZnO media by thermal treatment in oxygen ambient at temperatures in the range of ...

    Prominent retroreflection is experimentally observed in disordered porous InP membranes. It is believed to be the result of an interplay between Fresnel-like and Bragg-like reflection for different components of an impinging ...
  • Retroreflection of light from nanoporous InP: correlation with high absorption 
    PRISLOPSKI, S. Ya.; TIGINYANU, I. M.; GHIMPU, L.; MONAICO, E.; SIRBU, L.; GAPONENKO, S. V. (Springer Nature Switzerland, 2014)
    Pronounced retroreflection behavior is reported for a fishnet nanoporous strongly absorbing semiconductor material. Retroreflection appears along with diffusive specular reflection for all angles of incidence for light ...
  • Self-Assembled Monolayer of Au Nanodots Deposited on Porous Semiconductor Structures
