In the scope of the nanotechnologies development the epitaxial growth on /in porous substrates A3B5,(InP, GaAs and GaP) will be investigated. Micro and nanopores layers could improve the structural perfection of the highly mismatched heterojunction when mode of the lateral overgrowth is realized. Three particular applications of the porous layers will be studied. At first lateral overgrowth methode, secondly deposition of the heterojunction material into the pores area and micro/nanopores layers for the active structure separation from the substrate in case of multiple deposition of the struucture on the same substrate. Electrochemical technology of the micro/nano pores production in A3B5 semiconductors is a research subject in our laboratory for more than three years and epitaxial deposition of the A3B5 semiconductors from the vapor and liquid phase for optoelectronic devices has been investigated for nearly four decades. Research of the defects structure by electron microscopy , microcathodoluminescence and wet etching will be combined with low temperature PL and transport properties research.
