Interface dynamics and crystal phase switching in GaAs nanowires.

Nature

Jacobsson D, Panciera F, Tersoff J, Reuter MC, Lehmann S, Hofmann S, Dick KA, Ross FM.
PMID: 26983538
Nature. 2016 Mar 17;531(7594):317-22. doi: 10.1038/nature17148.

Controlled formation of non-equilibrium crystal structures is one of the most important challenges in crystal growth. Catalytically grown nanowires are ideal systems for studying the fundamental physics of phase selection, and could lead to new electronic applications based on...

Kinetics of individual nucleation events observed in nanoscale vapor-liquid-solid growth.

Science (New York, N.Y.)

Kim BJ, Tersoff J, Kodambaka S, Reuter MC, Stach EA, Ross FM.
PMID: 19008438
Science. 2008 Nov 14;322(5904):1070-3. doi: 10.1126/science.1163494.

We measured the nucleation and growth kinetics of solid silicon (Si) from liquid gold-silicon (AuSi) catalyst particles as the Si supersaturation increased, which is the first step of the vapor-liquid-solid growth of nanowires. Quantitative measurements agree well with a...

Interventional techniques in the management of chronic pain: Part 2.0.

Pain physician

Manchikanti L, Singh V, Kloth D, Slipman CW, Jasper JF, Trescot AM, Varley KG, Atluri SL, Giron C, Curran MJ, Rivera J, Baha AG, Bakhit CE, Reuter MW.
PMID: 16906171
Pain Physician. 2001 Jan;4(1):24-96.

The practice guidelines for interventional techniques in the management of chronic pain are systematically developed statements to assist physician and patient decisions about appropriate health care related to chronic pain. These guidelines are professionally derived recommendations for practices in...

Sawtooth faceting in silicon nanowires.

Physical review letters

Ross FM, Tersoff J, Reuter MC.
PMID: 16241673
Phys Rev Lett. 2005 Sep 30;95(14):146104. doi: 10.1103/PhysRevLett.95.146104. Epub 2005 Sep 29.

We observe in situ the vapor-liquid-solid (VLS) growth of Si nanowires, in UHV-CVD using Au catalyst. The nanowire sidewalls exhibit periodic sawtooth faceting, reflecting an oscillatory growth process. We interpret the facet alternation as resulting from the interplay of...

Closed-form Green functions, surface effects, and the importance of dimensionality in tight-binding metals.

The Journal of chemical physics

Reuter MG.
PMID: 20649346
J Chem Phys. 2010 Jul 21;133(3):034703. doi: 10.1063/1.3447960.

Closed-form expressions for all elements of a d-dimensional tight-binding metal's Green function matrix are presented and used to explore edge effects of a surface. We find that, when moving from the surface into the bulk, the number of layers...

Periodically changing morphology of the growth interface in Si, Ge, and GaP nanowires.

Physical review letters

Wen CY, Tersoff J, Hillerich K, Reuter MC, Park JH, Kodambaka S, Stach EA, Ross FM.
PMID: 21797618
Phys Rev Lett. 2011 Jul 08;107(2):025503. doi: 10.1103/PhysRevLett.107.025503. Epub 2011 Jul 06.

Nanowire growth in the standard direction is assumed to occur at a planar catalyst-nanowire interface, but recent reports contradict this picture. Here we show that a nonplanar growth interface is, in fact, a general phenomenon. Both III-V and group...

[Is theoretical physics in need of religious faith? Neo-scholasticism and positivism in the Third Republic].

Revue de synthese

Neuber M.
PMID: 23892651
Rev Synth. 2013;134(2):221-47. doi: 10.1007/s11873-013-0220-4.

As common wisdom has it, Pierre Duhem was one of the most important proponents of French philosophy of science around 1900. Usually, his conception of physical theories is regarded as the incarnation of the ancient - proto-positivistic - programme...

Strategies to control morphology in hybrid group III-V/group IV heterostructure nanowires.

Nano letters

Hillerich K, Dick KA, Wen CY, Reuter MC, Kodambaka S, Ross FM.
PMID: 23421434
Nano Lett. 2013 Mar 13;13(3):903-8. doi: 10.1021/nl303660h. Epub 2013 Feb 19.

By combining in situ and ex situ transmission electron microscopy measurements, we examine the factors that control the morphology of "hybrid" nanowires that include group III-V and group IV materials. We focus on one materials pair, GaP/Si, for which...

Estimating the Landauer-Büttiker transmission function from single molecule break junction experiments.

Nanotechnology

Tschudi SE, Reuter MG.
PMID: 27623441
Nanotechnology. 2016 Oct 21;27(42):425203. doi: 10.1088/0957-4484/27/42/425203. Epub 2016 Sep 13.

When investigating the electronic response properties of molecules, experiments often measure conductance whereas computation predicts the transmission probability. Although Landauer-Büttiker theory usually relates the two, comparison between experiment and computation remains difficult because experimental data (specifically those from break...

Dual Lewis Acid/Photoredox-Catalyzed Addition of Ketyl Radicals to Vinylogous Carbonates in the Synthesis of 2,6-Dioxabicyclo[3.3.0]octan-3-ones.

Organic letters

A combined Lewis acid/photoredox catalyst system enabled the intramolecular umpolung addition of ketyl radicals to vinylogous carbonates in the synthesis of 2,6-dioxabicyclo[3.3.0]octan-3-ones. This reaction proceeded on a variety of aromatic ketones to provide THF rings in good yield (up...
