Variation of the Electronic Functionality of Self-Seeded Germanium Nanowires through Synthesis Determined Core-Shell Interface States

چکیده

Bottom up grown germanium nanowires may have an important role to play in future electronic devices. While the electrical properties of nanowires grown using a metallic seed as a catalyst have been extensively reported we study self-seeded nanowires in this thesis. Such wires are core-shell in nature and are grown without any intentional doping. Self-seeded nanowires have been previously proposed as an attractive alternative to conventionally grown wires due the alleviation of complications arising from unintentional doping from the metallic seed. The results in this thesis demonstrate that the electrical properties of the self-seeded, core-shell nanowire are dominated by doping from the interfaces states which is in turn dependent on the details of the nanowire growth.

Metal-seeded growth of III-V semiconductor nanowires: towards gold-free synthesis.

Semiconductor nanowires composed of III-V materials have enormous potential to add new functionality to electronics and optical applications. However, integration of these promising structures into applications is severely limited by the current near-universal reliance on gold nanoparticles as seeds for nanowire fabrication. Although highly controlled fabrication is achieved, this metal is enti...

Vapor-liquid-solid and vapor-solid growth of phase-change Sb2Te3 nanowires and Sb2Te3/GeTe nanowire heterostructures.

We report the synthesis and characterization of radial heterostructures composed of an antimony telluride (Sb2Te3) core and a germanium telluride (GeTe) shell, as well as an improved synthesis of Sb2Te3 nanowires. The synthesis of the heterostructures employs Au-catalyst-assisted vapor-liquid-solid (VLS) and vapor-solid (VS) mechanisms. Energy-dispersive X-ray spectrometry indicates that Sb and...

Transport modulation in Ge/Si core/shell nanowires through controlled synthesis of doped Si shells.

Appropriately controlling the properties of the Si shell in Ge/Si core/shell nanowires permits not only passivation of the Ge surface states, but also introduces new interface phenomena, thereby enabling novel nanoelectronics concepts. Here, we report a rational synthesis of Ge/Si core/shell nanowires with doped Si shells. We demonstrate that the morphology and thickness of Si shells can be con...

Spatially resolved Raman spectroscopy on indium-catalyzed core-shell germanium nanowires: size effects.

The structure of indium-catalyzed germanium nanowires is investigated by atomic force microscopy, scanning confocal Raman spectroscopy and transmission electron microscopy. The nanowires are formed by a crystalline core and an amorphous shell. We find that the diameter of the crystalline core varies along the nanowire, down to few nanometers. Phonon confinement effects are observed in the regio...

Boosting Hole Mobility in Coherently Strained [110]-Oriented Ge–Si Core–Shell Nanowires

The ability of core-shell nanowires to overcome existing limitations of heterostructures is one of the key ingredients for the design of next generation devices. This requires a detailed understanding of the mechanism for strain relaxation in these systems in order to eliminate strain-induced defect formation and thus to boost important electronic properties such as carrier mobility. Here we de...
