Single-crystal germanium nanowires have been synthesized in the temperature range 380–430 °C without the use of any metal catalysts. Tetraethylgermane was used as a precursor in combination with different organic solvents to produce nanowires with controlled diameter ranging from 5 nm to 700 nm. The growth direction of nanowires is along <011> direction. The method is based on the vapor-liquid-solid mechanism, with the classical liquid-metal catalyst replaced by droplets of high-boiling-point hydrocarbons.

    A two-step process was developed to explore ways for massive production of inorganic nanowires (NWs) with well-defined morphology. The first-step vapor-liquid-solid (VLS) growth defined the lateral dimension of boron NWs using Au–B catalytic tips, which was terminated with a quench to...

    Step bunching at a growing crystal surface is usually attributed to the presence of the Ehrlich–Schwoebel (ES) effect caused by the asymmetry of the attachment kinetics at a step. Here, we show that, contrary to the case of rectilinear motion, step bunches at the solid-liquid interface of...

    The effect of Ti additions on the wetting behavior of CaF2 by non-reactive liquid metals (In, Sn, Ga, Au, Ge) was investigated. Pure metals do not wet CaF2 while minor additions of Ti improve wetting. Small changes of the contact angle were observed in the CaF2/Au–Ti and CaF2/Ge–Ti...

    Approximated equations have been constructed to describe the temperature ( T) dependence of the molar volumes ( V) of fcc solid metals (Ag, Al, Au, Cu, Ir, Ni, Pb, Pd, Pt, and Rh) and their liquids below and above their melting points at standard pressure of 1 bar from zero Kelvin. Below the...

    For some elements such as germanium or tin, the mass spectra of ions emitted by liquid metal ion sources (LMIS) exhibit periodicities, i.e. series of equidistant peaks with an increase, ν, in the number of atoms between two peaks. We attribute it to the existence of jets in operating LMIS,...

    Silicon nanowires have been identified as important components for future electronic and sensor nanodevices. So far gold has dominated as the catalyst for growing Si nanowires via the vapour–liquid–solid (VLS) mechanism. Unfortunately, gold traps electrons and holes in Si and poses...

    We report detailed structural analysis of 〈111〉 oriented silicon nanowires (NWs) grown by UHV-CVD using the VLS process with a gold catalyst. STEM-HAADF observations have revealed an unexpected inhomogeneous distribution of gold nanoclusters on the NW surface. Gold is mainly...

    We present a refined model for the vapor-liquid-solid growth and crystal structure of Au-catalyzed I I I -V nanowires, which revisits several assumptions used so far and is capable of describing the transition from mononuclear to polynuclear regime and ultimately to regular atomistic growth. We...

    Using nonequilibrium molecular dynamics simulations in which a temperature gradient is imposed, we determine the thermal resistance of a model liquid-solid interface. Our simulations reveal that the strength of the bonding between liquid and solid atoms plays a key role in determining...
