Spin-galvanic effect due to optical spin orientation
Sergey Ganichev,Petra Schneider,V. V. Bel'kov,E. L. Ivchenko,Sergey Tarasenko,Werner Wegscheider,Dieter Weiss,Dieter Schuh,B. N. Murdin,P. J. Phillips,C. R. Pidgeon,D. G. Clarke,M. Merrick,P. Murzyn,E. Beregulin,Wilhelm Prettl +15 more
TL;DR: In this paper, the spin-galvanic effect has been unambiguously observed in (001)-grown $n$-type GaAs quantum well (QW) structures in the absence of any external magnetic field.

TL;DR: In this article, the authors report the direct determination of nonradiative lifetimes in Si∕SiGe asymmetric quantum well structures designed to access spatially indirect (diagonal) interwell transitions between heavy-hole ground states, at photon energies below the optical phonon energy.

Intersublevel polaron dephasing in self-assembled quantum dots
E. A. Zibik,Thomas Grange,B. A. Carpenter,R. Ferreira,G. Bastard,Nguyen Q. Vinh,P. J. Phillips,M. J. Steer,Mark Hopkinson,John W. Cockburn,M. S. Skolnick,Luke R. Wilson +11 more
TL;DR: In this article, the authors show that both real and virtual acoustic phonon processes are necessary to explain the temperature dependence of the polarization decay in InAs/GaAs dots using far-infrared transient four wave mixing (FWM) spectroscopy.

Electron spin lifetimes in long-wavelength Hg 1-x Cd x Te and InSb at elevated temperature
P. Murzyn,C. R. Pidgeon,P. J. Phillips,JP Wells,Neil Gordon,Timothy Ashley,John H. Jefferson,T. M. Burke,Jean Giess,M. Merrick,B. N. Murdin,C. D. Maxey +11 more
TL;DR: In this paper, the authors measured the spin lifetimes in long-wavelength narrow-gap semiconductors at wavelengths between 4 and 10 µm and from 4 to 300 K.
21
Suppression of D'yakonov-Perel spin relaxation in InAs and insb by n-type doping at 300 K
P. Murzyn,C. R. Pidgeon,P. J. Phillips,M. Merrick,Konstantin Litvinenko,Jeremy Allam,B. N. Murdin,Timothy Ashley,John H. Jefferson,Alan Miller,Lesley F. Cohen +10 more
TL;DR: In this paper, the authors measured remarkably long spin lifetimes (tau(s)similar to 1.6 ns) for near-degenerate epilayers of n-InAs.
