This thesis is devoted to the study of HVPE (Hydride Vapour Phase Epitaxy) method of growing GaN and GaAs nanowires with and without catalyst. A systematic study of the influence of the growth conditions on GaN formation was performed in order to demonstrate the feasibility of this growth on c-plane sapphire and silicon substrates without preliminary treatment of the surface. We have demonstrated by VLS-HVPE the growth of the GaN nanowires with constant diameters of 40 to 200 nm and of length up to 60 μm, while they possess remarkable optical and crystal quality. The newly observed stability of the zinc blende structure for GaAs nanowires with diameters of 10 nm has been described by the VLS-HVPE process, for lengths of few tens of micromet...
