Periodic exciton–polariton solitons in semiconductor nanowires

Acoustic solitons in semiconductor nanostructures

The present lecture gives the review of recent studies where acoustic solitons strongly influence the electron states in a semiconductor nanostructure. The amplitude of soliton pulses is so high that the electron states in a quantum well make temporal excursions in energy up to 10 meV. The subpicosecond duration of the solitons is less than the coherence time of the optical transition between t...

Ballistic superconductivity in semiconductor nanowires

Semiconductor nanowires have opened new research avenues in quantum transport owing to their confined geometry and electrostatic tunability. They have offered an exceptional testbed for superconductivity, leading to the realization of hybrid systems combining the macroscopic quantum properties of superconductors with the possibility to control charges down to a single electron. These advances b...

Thermal Transport in Semiconductor Nanowires

Metal-catalyzed semiconductor nanowires

Semiconductor nanowires have become an important building block for nanotechnology. The growth of semiconductor nanowires using a metal catalyst via the vapor–liquid–solid (VLS) or vapor–solid–solid (VSS) mechanism has yielded growth directions in 〈1 1 1〉, 〈1 0 0〉 and 〈1 1 0〉 etc. In this paper, we summarize and discuss a broad range of factors that affect the growth direction of VLS or VSS gro...

TOPICAL REVIEW Semiconductor nanowires

Semiconductor nanowires (NWs) represent a unique system for exploring phenomena at the nanoscale and are also expected to play a critical role in future electronic and optoelectronic devices. Here we review recent advances in growth, characterization, assembly and integration of chemically synthesized, atomic scale semiconductor NWs. We first introduce a general scheme based on a metal-cluster ...
