Growth and optical properties of axial hybrid III-V/silicon nanowires.

Nature communications

Hocevar M, Immink G, Verheijen M, Akopian N, Zwiller V, Kouwenhoven L, Bakkers E.
PMID: 23232396
Nat Commun. 2012;3:1266. doi: 10.1038/ncomms2277.

Hybrid silicon nanowires with an integrated light-emitting segment can significantly advance nanoelectronics and nanophotonics. They would combine transport and optical characteristics in a nanoscale device, which can operate in the fundamental single-electron and single-photon regime. III-V materials, such as...

Wide InP nanowires with wurtzite/zincblende superlattice segments are type-II whereas narrower nanowires become type-I: an atomistic pseudopotential calculation.

Nanowire-superlattices with different structural phases along the nanowire direction, such as wurtzite (WZ) and zincblende (ZB) forms of the same compound, often exhibit a "type II" band-alignment with electrons on ZB and holes on WZ. This is a material...

We aimed to assess the efficacy and safety of minimally invasive percutaneous nephrolithotomy (PCNL) with SuperPulsed Thulium-fiber laser (SP TFL) using different frequency settings. 125 patients with solitary kidney calculi of up to 55 mm in the maximum diameter...

Bright single-photon sources in bottom-up tailored nanowires.

Nature communications

Reimer ME, Bulgarini G, Akopian N, Hocevar M, Bavinck MB, Verheijen MA, Bakkers EP, Kouwenhoven LP, Zwiller V.
PMID: 22415828
Nat Commun. 2012 Mar 13;3:737. doi: 10.1038/ncomms1746.

The ability to achieve near-unity light-extraction efficiency is necessary for a truly deterministic single-photon source. The most promising method to reach such high efficiencies is based on embedding single-photon emitters in tapered photonic waveguides defined by top-down etching techniques....

Investigating the spatial distribution of genetic and phenotypic variation can provide insights into the evolutionary processes that shape diversity in natural systems. We characterized patterns of genetic and phenotypic diversity to learn about drivers of color-pattern diversification in red-eyed...
