Journal ArticleDOI
Auger recombination dynamics of lead salts under picosecond free-electron-laser excitation
P. C. Findlay,C. R. Pidgeon,R. T. Kotitschke,A. R. Hollingworth,B. N. Murdin,C J G M Langerak,A.F.G. van der Meer,C. M. Ciesla,Josef Oswald,A. Homer,Gunther Springholz,G. Bauer +11 more
TL;DR: In this paper, a pump-probe transmission experiment was performed on PbSe above the fundamental absorption edge near 4 \ensuremath{mu}m in the temperature range 30 to 300 K, using the Dutch ps free-electron laser.
Journal ArticleDOI
Suppression of lo phonon scattering in landau quantized quantum dots
B. N. Murdin,A. R. Hollingworth,M. Kamal-Saadi,R. T. Kotitschke,C. M. Ciesla,C. R. Pidgeon,P. C. Findlay,H. Pellemans,C J G M Langerak,Alistair Rowe,R. A. Stradling,Erich Gornik +11 more
TL;DR: In this paper, the scattering between conduction-band states in a doped quasi-quantum dot was investigated, and a clear suppression of the cooling rate was seen, from 1012 s-1 when the level spacing is equal to the phonon energy, to 1010 s −1 away from this resonance.
Journal ArticleDOI
Double-resonance spectroscopy of InAs/GaAs self-assembled quantum dots
B. N. Murdin,A. R. Hollingworth,J. A. Barker,D. G. Clarke,P. C. Findlay,C. R. Pidgeon,Jon-Paul R. Wells,I. V. Bradley,S. Malik,R. Murray +9 more
TL;DR: In this paper, the authors present far/near-infrared double resonance measurements of self-assembled InAs/GaAs quantum dots and show that the interband photoluminescence lines originate from conduction levels with successively increasing in-plane quantum numbers.

Journal ArticleDOI
Influence of Auger and LO-phonon scattering on bulk and 'quasi'-quantum wire mid-IR laser diodes
R. T. Kotitschke,A. R. Hollingworth,Eoin P. O'Reilly,Alf R. Adams,B. N. Murdin,C.T. Elliott,C J G M Langerak,P. C. Findlay,C. R. Pidgeon,T. Ashley,Graham John Pryce +10 more
TL;DR: In this article, measurements of the light-current characteristics of bulk InSb and InAlSb have been made in the temperature range from 4.2 to 110K, where the authors found values of the characteristic temperature T 0 of around 22K above 90K, indicating that Auger recombination is dominant, but T 0 increasing to around 45K at lower temperatures.
