Theoretical study of high-density phases of covalent semiconductors. I. Ab initio treatment. (1994)
Journal Article
Crain, J., Clark, S., Ackland, G., Payne, M., Milman, V., Hatton, P., & Reid, B. (1994). Theoretical study of high-density phases of covalent semiconductors. I. Ab initio treatment. Physical Review B (Condensed Matter), 49(8), 5329-5340. https://doi.org/10.1103/physrevb.49.5329

We present detailed calculations using the total-energy pseudopotential method in the local-density approximation of the relative stability and pressure-induced behavior of complex tetrahedrally bonded structures formed metastably in silicon and germ...

Theoretical study of high-density phases of covalent semiconductors. II. Empirical treatment. (1994)
Journal Article
Clark, S., Ackland, G., & Crain, J. (1994). Theoretical study of high-density phases of covalent semiconductors. II. Empirical treatment. Physical Review B (Condensed Matter), 49(8), 5341-5352. https://doi.org/10.1103/physrevb.49.5341

We show that a simple pairwise model for covalent materials provides a good description of the high-density fourfold-coordinated metastable phases BC8 and ST12, in agreement with experimental results and ab initio calculations. We use this potential... Read More about Theoretical study of high-density phases of covalent semiconductors. II. Empirical treatment..

Atom Optics. (1994)
Journal Article
Adams, C. (1994). Atom Optics. Contemporary Physics, 35(1), 1-19. https://doi.org/10.1080/00107519408217492

The field of atom optics has enjoyed a surge of interest in recent years because of the production of microstructures sufficiently fine to diffract atomic beams through significant angles, and the development of tunable narrow-linewidth lasers that c... Read More about Atom Optics..

VAPOR RECOGNITION USING ORGANIC FILMS AND ARTIFICIAL NEURAL NETWORKS (1994)
Journal Article
Barker, P., Chen, J., Agbor, N., Monkman, A., Mars, P., & Petty, M. (1994). VAPOR RECOGNITION USING ORGANIC FILMS AND ARTIFICIAL NEURAL NETWORKS. Sensors and Actuators B: Chemical, 17(2), 143-147

Organic thin-film sensors based on the thermal evaporation and dip-coating of polyaniline, and on the Langmuir-Blodgett deposition of a vanadium porphyrin, have been fabricated. The d.c. electrical resistances of the individual elements are found to... Read More about VAPOR RECOGNITION USING ORGANIC FILMS AND ARTIFICIAL NEURAL NETWORKS.
