Zhu T, Ding T, Tang F, Han Y, Ali M, Badcock T, et al.
Cryst Growth Des . 2016 Apr; 16(2):1010-1016. PMID: 27065755
Non- and semipolar GaN have great potential to improve the efficiency of light emitting devices due to much reduced internal electric fields. However, heteroepitaxial GaN growth in these crystal orientations...

Sharma M, Sanyal M, Farrer I, Ritchie D, Dey A, Bhattacharyya A, et al.
Sci Rep . 2015 Oct; 5:15732. PMID: 26506865
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...

Frohlich B, Dynes J, Lucamarini M, Sharpe A, Yuan Z, Shields A
Nature . 2013 Sep; 501(7465):69-72. PMID: 24005413
The theoretically proven security of quantum key distribution (QKD) could revolutionize the way in which information exchange is protected in the future. Several field tests of QKD have proven it...

Bennett A, Pooley M, Cao Y, Skold N, Farrer I, Ritchie D, et al.
Nat Commun . 2013 Feb; 4:1522. PMID: 23443550
Single spins in the solid state offer a unique opportunity to store and manipulate quantum information, and to perform quantum-enhanced sensing of local fields and charges. Optical control of these...

Schwagmann A, Kalliakos S, Ellis D, Farrer I, Griffiths J, Jones G, et al.
Opt Express . 2012 Dec; 20(27):28614-24. PMID: 23263099
We report on the design and experimental demonstration of a system based on an L3 cavity coupled to a photonic crystal waveguide for in-plane single-photon emission. A theoretical and experimental...

Lawton E, Shields A, Oltmanns T
Personal Disord . 2011 Dec; 2(4):279-92. PMID: 22200006
The need for an empirically validated, dimensional system of personality disorders is becoming increasingly apparent. While a number of systems have been investigated in this regard, the five-factor model of...

Skiba-Szymanska J, Jamil A, Farrer I, Ward M, Nicoll C, Ellis D, et al.
Nanotechnology . 2011 Jan; 22(6):065302. PMID: 21212488
We report photoluminescence measurements on a single layer of site-controlled InAs quantum dots (QDs) grown by molecular beam epitaxy (MBE) on pre-patterned GaAs(100) substrates with a 15 nm re-growth buffer...

Patel R, Bennett A, Cooper K, Atkinson P, Nicoll C, Ritchie D, et al.
Nanotechnology . 2010 Jun; 21(27):274011. PMID: 20571198
Quantum interference lies at the foundation of many protocols for scalable quantum computing and communication with linear optics. To observe these effects the light source must emit photons that are...

Stevenson R, Hudson A, Bennett A, Young R, Nicoll C, Ritchie D, et al.
Phys Rev Lett . 2008 Nov; 101(17):170501. PMID: 18999730
We investigate the evolution of quantum correlations over the lifetime of a multiphoton state. Measurements reveal time-dependent oscillations of the entanglement fidelity for photon pairs created by a single semiconductor...
