  • Controlling the Degree of Hydrophilicity/Hydrophobicity of Semiconductor Surfaces via Porosification and Metal Deposition 
    MONAICO, E. V.; BUSUIOC, S.; TIGINYANU, I. M. (Springer, Cham, 2022)
    In this paper we present a systematic study of bulk GaAs wafers and gold-decorated GaAs surfaces exhibiting hydrophilic and hydrophobic behaviors. The wetting properties can be switched to superhydrophilicity and ...
  • Development of Conductive Nanotemplates on ZnSe 
    MONAICO, Eduard; TIGINYANU, Ion; COLIBABA, Gleb; NEDEOGLO, D. D.; COJOCARU, Ala; FÖLL, Helmut (Technical University of Moldova, 2011)
    We demonstrate the possibility to fabricate arrays of pores oriented perpendicular and parallel to the top surface of the ZnSe nanotemplate. The control of material conductivity allows one to produce porous ZnSe samples ...
  • Investigation of Mesoporous Structures for Thermoelectric Applications 
    COJOCARU, A.; CARSTENSEN, J.; BOOR, J.; SCHMIDT, V.; FÖLL, H. (Technical University of Moldova, 2011)
    Mesoporous silicon is an attractive material for thermoelectric application. For pore wall thicknesses around <100nm, phonons can not penetrate the porous layer while electrons still can, due to there smaller mean free ...
  • Monte-Carlo-Simulation of Crystallographical Pore Growth in III-V-Semiconductors 
    LEISNER, Malte; CARSTENSEN, Jürgen; FÖLL, Helmut (Technical University of Moldova, 2011)
    The growth of crystallographical pores in III-V-semiconductors can be understood in the framework of a simple model, which is based on the assumption that the branching of pores is proportional to the current density at ...
  • The Role of Alternating Current in Photo-Assisted Electrochemical Porosification of GaN 
    MAHMOOD, Ainorkhilah; AHMED, Naser M.; TIGINYANU, Ion; YUSOF, Yushamdan; KWONG, Yam Fong; SIANG, Chuah Lee; HASSAN, Zainuriah (Technical University of Moldova, 2013)
    In this paper, we report the formation of porous GaN films under a novel alternating current (sine-wave a.c. (50 Hz)) photo-assisted electrochemical (ACPEC) etching conditions. The ACPEC formed porous GaN with excellent ...
