Spin Relaxation by Transient Monopolar and Bipolar Optical Orientation (2006)

Murdin, B. N., Litvinenko, K., Clarke, D. G., Pidgeon, C. R., Murzyn, P., Phillips, P. J., ...

We have used two-color time-resolved spectroscopy to measure the relaxation of electron spin polarizations in a bulk semiconductor. The circularly polarized pump beam induces a polarization either by...

Excitonic signatures in the photoluminescence and terahertz absorption of a GaAs/AlxGa1-xAs multiple quantum well (2005)

Galbraith, I., Chari, R., Pellegrini, S., Phillips, P. J., Dent, C. J., ...

Measurements of the THz absorption and the time-resolved photoluminescence have been performed on the same GaAs quantum well sample. The strength of the absorption at the internal 1s-2p exciton...

Excitonic Signatures in the Photoluminescence and Terahertz Absorption of a GaAs/AlxGa1-xAs Multiple Quantum Well (2005)

Galbraith, I, Chari, R, Pellegrini, S, Phillips, P J, Dent, C J, Van Der Meer, A F, ...

Measurements of the THz absorption and the time-resolved photoluminescence have been performed on the same GaAs quantum well sample. The strength of the absorption at the internal 1s-2p exciton...

Spin-galvanic effect due to optical spin orientation in n-type GaAs quantum well structures (2003)

Ganichev, S. D., Schneider, Petra, Bel'kov, V. V., Ivchenko, E. L., Tarasenko, S. A., Wegscheider, W., ...

Under oblique incidence of circularly polarized infrared radiation the spin-galvanic effect (SGE) has been unambiguously observed in (001)-grown n-type GaAs quantum well structures in the absence of...

Excitonic signatures in photoluminescence and terahertz absorption (2003)

Chari, R., Galbraith, I., Phillips, J., Pellegrini, S., Dent, C. J., Kar, A. K., ...

By measuring THz absorption and time-resolved photoluminescence on the same GaAs quantum well sample we confirm the recent prediction of Kira that PL at the exciton frequency does not require a...

Spin-galvanic effect due to optical spin orientation (2003)

Ganichev, S. D., Schneider, Petra, Bel'kov, V. V., Ivchenko, E. L., Tarasenko, S. A., Wegscheider, W., ...

Under oblique incidence of circularly polarized infrared radiation the spin-galvanic effect has been unambiguously observed in (001)-grown $n$-type GaAs quantum well (QW) structures in the absence of...

The effect of pressure on the radiative efficiency of InAs based light emitting diodes. . (2003)

Choulis, S. A., Andreev, A., Merrick, M., Jin, S., Clarke, D. G., Murdin, B. N., ...

The spontaneous emission of 3.3 mum light emitting diodes (LEDs) and lasers based on InAs alloys were studied as a function of hydrostatic pressure. An increase in light output with increasing...

External Uniqueness is Unique Enough (2002)

Clarke, D.G., Wrigstad, T

External uniqueness is a surprising new way to add unique references to an OOPL. The idea is that an externally unique reference is the only reference into an aggregate from outside the aggregate....

Double-resonance spectroscopy of InAsÕGaAs self-assembled quantum dots (2000)

Murdin, B. N., Hollingworth, A. R., Barker, J. A., Clarke, D. G., Findlay, P. C., Pidgeon, C. R., ...

We present far-/near-infrared double resonance measurements of self-assembled InAs/GaAs quantum dots. The far-infrared resonance is unambiguously associated with a bound-bound intraband transition in...

Acoustic Characterization of Suspended Sediment Plumes Resulting from Barge Overflow (1998)

Reine, K. J., Clarke, D. G., Dickerson, C.

This technical note presents the results of acoustic monitoring of suspended sediment plumes resulting from overflow from hydraulically filled barges during dredging operations in the Cape Fear...

Strongyloides stercoralis hyperinfection associated with cimetidine in an immunosuppressed patient: diagnosis by endoscopic biopsy.

Ainley, C C, Clarke, D G, Timothy, A R, Thompson, R P

Immunosuppression causes Strongyloides stercoralis hyperinfection, but other factors may also be involved. We report a case of S stercoralis hyperinfection in an immunosuppressed patient that...
