Growth and characterization of germanium nanowires on a flexible aluminium substrate by electron beam evaporation

Growth of Germanium Nanowires on a Flexible Organic Substrate

Silicon nanowires prepared by electron beam evaporation in ultrahigh vacuum

One-dimensional silicon nanowires (SiNWs) were prepared by electron beam evaporation in ultrahigh vacuum (UHV). The SiNWs can be grown through either vapor-liquid-solid (VLS) or oxide-assisted growth (OAG) mechanism. In VLS growth, SiNWs can be formed on Si surface, not on SiO2 surfaces. Moreover, low deposition rate is helpful for producing lateral SiNWs by VLS. But in OAG process, SiNWs can b...

Size controlled growth of germanium nanorods and nanowires by solution pyrolysis directly on a substrate.

Herein, we describe the controlled growth of 1 dimensional germanium nanostructures from high aspect ratio nanowires (>10 microns in length) to shorter aspect nanorods (100 nm in length) via a simple pyrolysis method. The synthetic route involves the thermal decomposition of selected germanium precursors by dropping a solution in a high boiling point solvent directly onto a pre-heated Si wafer ...

Kinetics of Si and Ge nanowires growth through electron beam evaporation

Si and Ge have the same crystalline structure, and although Si-Au and Ge-Au binary alloys are thermodynamically similar (same phase diagram, with the eutectic temperature of about 360°C), in this study, it is proved that Si and Ge nanowires (NWs) growth by electron beam evaporation occurs in very different temperature ranges and fluence regimes. In particular, it is demonstrated that Ge growth ...

Growth of germanium nanowires on silicon(111) substrates by molecular beam epitaxy.

Heteroepitaxial growth of Ge nanowires was carried out on Si(111) substrates by MBE. Au seeds were used as precursor for the VLS growth of the nanowires. Even if the Au droplets do not act as catalyst for the dissociation of gas, they are local preferential areas where the energetic barrier of Ge nucleation is lowered compare to the remaining non activated surface. Two sets of Au seeds were use...
