Time-of-Flight Measurements of Single-Electron Wave Packets in Quantum Hall Edge States.

Physical review letters

Kataoka M, Johnson N, Emary C, See P, Griffiths JP, Jones GA, Farrer I, Ritchie DA, Pepper M, Janssen TJ.
PMID: 27058091
Phys Rev Lett. 2016 Mar 25;116(12):126803. doi: 10.1103/PhysRevLett.116.126803. Epub 2016 Mar 22.

We report time-of-flight measurements on electrons traveling in quantum Hall edge states. Hot-electron wave packets are emitted one per cycle into edge states formed along a depleted sample boundary. The electron arrival time is detected by driving a detector...

Spin-Dependent Transport in Fe/GaAs(100)/Fe Vertical Spin-Valves.

Scientific reports

Wong PK, Zhang W, Wu J, Will IG, Xu Y, Xia K, Holmes SN, Farrer I, Beere HE, Ritchie DA.
PMID: 27432047
Sci Rep. 2016 Jul 19;6:29845. doi: 10.1038/srep29845.

The integration of magnetic materials with semiconductors will lead to the development of the next spintronics devices such as spin field effect transistor (SFET), which is capable of both data storage and processing. While the fabrication and transport studies...

Coherent detection of THz laser signals in optical fiber systems.

Optics express

Folland TG, Marshall OP, Beere HE, Ritchie DA, Chakraborty S.
PMID: 29041222
Opt Express. 2017 Oct 16;25(21):25566-25573. doi: 10.1364/OE.25.025566.

Terahertz (THz) coherent detectors are crucial for the stabilization and measurement of the properties of quantum cascade lasers (QCLs). This paper describes the exploitation of intra-cavity sum frequency generation to up-convert the emission of a THz QCL to the...

Density dependent composition of InAs quantum dots extracted from grazing incidence x-ray diffraction measurements.

Scientific reports

Sharma M, Sanyal MK, Farrer I, Ritchie DA, Dey AB, Bhattacharyya A, Seeck OH, Skiba-Szymanska J, Felle M, Bennett AJ, Shields AJ.
PMID: 26506865
Sci Rep. 2015 Oct 28;5:15732. doi: 10.1038/srep15732.

Epitaxial InAs quantum dots grown on GaAs substrate are being used in several applications ranging from quantum communications to solar cells. The growth mechanism of these dots also helps us to explore fundamental aspects of self-organized processes. Here we...

Exertional Compartment Syndrome of the Medial Foot Compartment: Diagnosis and Treatment.

Journal of the American Podiatric Medical Association

Izadi FE, Richie DH.
PMID: 24963970
J Am Podiatr Med Assoc. 2014 Jun 25; doi: 10.7547/13-025.1. Epub 2014 Jun 25.

Exertional compartment syndrome (ECS) in the foot is rarely reported and often confused with plantar fasciitis as a cause of arch pain in the running athlete. We describe a case involving a 19 year old competitive collegiate runner who...

Quantum teleportation of laser-generated photons with an entangled-light-emitting diode.

Nature communications

Stevenson RM, Nilsson J, Bennett AJ, Skiba-Szymanska J, Farrer I, Ritchie DA, Shields AJ.
PMID: 24300834
Nat Commun. 2013;4:2859. doi: 10.1038/ncomms3859.

Quantum teleportation can transfer information between physical systems, which is essential for engineering quantum networks. Of the many technologies being investigated to host quantum bits, photons have obvious advantages as 'pure' quantum information carriers, but their bandwidth and energy...

The first international mini-symposium on methionine restriction and lifespan.

Frontiers in genetics

Ables GP, Brown-Borg HM, Buffenstein R, Church CD, Elshorbagy AK, Gladyshev VN, Huang TH, Miller RA, Mitchell JR, Richie JP, Rogina B, Stipanuk MH, Orentreich DS, Orentreich N.
PMID: 24847356
Front Genet. 2014 May 09;5:122. doi: 10.3389/fgene.2014.00122. eCollection 2014.

It has been 20 years since the Orentreich Foundation for the Advancement of Science, under the leadership Dr. Norman Orentreich, first reported that low methionine (Met) ingestion by rats extends lifespan (Orentreich et al., 1993). Since then, several studies...

Efficient coupling of double-metal terahertz quantum cascade lasers to flexible dielectric-lined hollow metallic waveguides.

Optics express

Wallis R, Degl'Iinnocenti R, Jessop DS, Ren Y, Klimont A, Shah YD, Mitrofanov O, Bledt CM, Melzer JE, Harrington JA, Beere HE, Ritchie DA.
PMID: 26480141
Opt Express. 2015 Oct 05;23(20):26276-87. doi: 10.1364/OE.23.026276.

The growth in terahertz frequency applications utilising the quantum cascade laser is hampered by a lack of targeted power delivery solutions over large distances (>100 mm). Here we demonstrate the efficient coupling of double-metal quantum cascade lasers into flexible...
