  • Control of HVPE grown GaN nanostruturing by anodization 
    MONAICO, Ed.; MOISE, C.; MIHAI, G.; ENACHESCU, M.; NIELSCH, K.; URSAKI, V. V.; TIGINYANU, I. M. (Institutul de Fizică Aplicată, AŞM, 2018)
    In this paper, results of a systematic study of morphologies obtained with anodization in HNO3, HCl, and NaCl solutions are presented. It is shown that complex pyramidal structures composed by regions with modulated porosity ...
  • Control of persistent photoconductivity in nanostructured InP through morphology design 
    MONAICO, Ed.; POSTOLACHE, V.; BORODIN, E.; URSAKI, V. V.; LUPAN, O.; ADELUNG, R.; NIELSCH, K.; TIGINYANU, I. M. (IOP Publishing Ltd, 2015)
    In this paper, we show that long-duration-photoconductivity decay (LDPCD) and persistent photoconductivity (PPC) in porous InP structures fabricated by anodic etching of bulk substrates can be controlled through the ...
  • “Dark” modes backscattering as possible rationale for anomalous retroreflection from strongly absorbing porous nanostructures 
    SERGENTU, V. V.; URSAKI, V.; MONAICO, Ed.; TIGINYANU, I. M.; PRISLOPSKI, S. Ya.; GAPONENKO, S. V. (World Scientific, 2017)
    The previously discovered anomalous retroreflection in a strongly absorbing nanostructured medium is explained by using “dark” and “bright” modes. The consideration provides rationale not only for the retroreflection itself ...
  • Electrochemical Deposition by Design of Metal Nanostructures 
    MONAICO, Ed.; MONAICO, E. I.; URSAKI, V. V.; TIGINYANU, I. M.; NIELSCH, K. (Springer Nature Switzerland, 2019)
    We report on the application of specially-designed masks for the purpose of electrochemical etching of InP single crystals which enables one to change in a controlled fashion the direction of propagation of pores, including ...
  • GaAs nanowires obtained via electrochemical etching of bulk substrates 
    MONAICO, Ed.; MORARI, V.; URSAKI, V. V.; MONAICO, E. I.; TIGINYANU, I. M.; NIELSCH, K. (Institutul de Fizică Aplicată, AŞM, 2018)
    Technological conditions for obtaining InP nanomembranes and nanowires by means of fast anodic etching of bulk substrates have been recently elaborated. Electrochemical etching is an easy, cost-effective, and very fast ...
  • Multilayer porous structures of HVPE and MOCVD grown GaN for photonic applications 
    BRANISTE, T.; CIERS, Joachim; MONAICO, Ed.; MARTIN, D.; CARLIN, J.-F.; URSAKI, V. V.; SERGENTU, V. V.; TIGINYANU, I. M.; GRANDJEAN, N. (ELSEVIER, 2017)
    In this paper we report on a comparative study of electrochemical processes for the preparation of multilayer porous structures in hydride vapor phase epitaxy (HVPE) and metal organic chemical vapor phase deposition (MOCVD) ...
  • Towards Uniform Electrochemical Porosification of Bulk HVPE-Grown GaN 
    MONAICO, Ed.; MOISE, C.; MIHAI, G.; URSAKI, V. V.; LEISTNER, K.; TIGINYANU, I. M.; ENACHESCU, M.; NIELSCH, K. (The Electrochemical Society, 2019)
    In this paper, we report on results of a systematic study of porous morphologies obtained using anodization of HVPE-grown crystalline GaN wafers in HNO3, HCl, and NaCl solutions. The anodization-induced nanostructuring is ...
