Z User Workshop, London 1992 : Proceedings of the Seventh Annual Z User Meeting, London 14–15 December 1992
Autor: J.P. Bowen, J.E. Nicholls
The Z notation has been developed at the Programming Research Group at the Oxford University Computing Laboratory and elsewhere for over a decade. It is now used by industry as part of the software (and hardware) development process in both Europe an

Pulsed laser deposition of small molecules for organic electroluminescence
Autor: Panagiotis Vlachos, S. R. Farrar, Mary O'Neill, Stephen M. Kelly, A.J. Eastwood, Gary J. Richards, A. E. A. Contoret, J.E. Nicholls
Publikováno v: Applied Surface Science. 186:435-440
A XeCl excimer laser at 308 nm is used for the pulsed laser deposition (PLD) of a range of novel electroluminescent molecules. An optimum fluence dependent on the absorption length is found as a compromise between deposition rate and photodecompositi

CdTe Nanocrystals: Synthesis, Optical Characterization, and Pseudopotential Calculation of the Band Gap
Autor: T. Stirner, N. T. Kirkman, J.E. Nicholls, L. May, Colin Ellis, J. H. C. Hogg, Mary O'Neill, Stephen Malcolm Kelly
Publikováno v: Journal of Nanoscience and Nanotechnology. 1:451-455
CdTe nanocrystals were synthesized in aqueous solution using 1-thioglycerol and 2-mercaptoethanol as surface stabilizers. The nanocrystals were characterized by means of X-ray powder diffraction and UV-vis absorption measurements. The UV-vis absorpti

Excimer laser induced diffusion in magnetic semiconductor quantum wells
Autor: W.E. Hagston, J.E. Nicholls, H. Howari, T. Stirner, David Sands, J. H. C. Hogg
Publikováno v: Journal of Applied Physics. 88:1373-1379
Studies of pulsed laser annealing (PLA) of CdTe/CdMnTe quantum well structures are made in order to examine depth dependent effects in laser irradiated semiconductors. Since diffusion coefficients are strongly dependent on the temperature, depth reso

Spectroscopic evidence for different laser gain mechanisms in optically pumped ZnCdS/ZnS quantum well structures
Autor: J. H. C. Hogg, J.E. Nicholls, D.E. Ashenford, Mary O'Neill, B. Lunn, T. Stirner, P. Chen
Publikováno v: Journal of Applied Physics. 84:5621-5625
The role of biexcitons has been studied in two optically pumped quantum well (QW) structures of Zn1−xCdxS/ZnS, one with 18% Cd concentration and the other with 3% in the wells. For the x=18% QW structure, high excitation photoluminescence and stimu

Anisotropic Zeeman splitting in semimagnetic quantum-well structures
Autor: M. Happ, D.E. Ashenford, Wolfram Heimbrodt, J.E. Nicholls, B. Lunn, F. Neugebauer, C. Santos, Dieter Suisky
Publikováno v: Physical Review B. 58:3969-3976
The Zeeman splitting pattern in semimagnetic superlattices and asymmetric double quantum wells composed of different sequences of semimagnetic and nonmagnetic well and barrier materials have been investigated experimentally and theoretically, in part
