Electronic transport in alkali halides containing F centres

Autor: J W Hodby, G T Jenkin, J G Crowder, D W Stacey

Publikováno v: Journal of Physics C: Solid State Physics. 11:1841-1856

The trapping by F-centres of conduction electrons in KBr, KCl, KI, RbCl and RbI is studied via their photoconductivity at low temperature and in high magnetic fields. In zero magnetic field the carrier lifetime before final trapping is found to appro

Precise location of hydrogen atoms in complicated structures by diffraction of polarized neutrons from dynamically polarized nuclei

Autor: J. B. Hayter, Maurice Leslie, G. Warner, S. Cox, J.W. White, G. T. Jenkin

Publikováno v: Philosophical Transactions of the Royal Society of London. B, Biological Sciences. 290:497-503

The first results are reported on the precise location of hydrogen atoms in a complicated crystal structure by using diffraction of polarized neutrons from dynamically polarized protons in the sample. Two methodologies exploiting the spin-dependent s

Cyclotron resonance of polarons in KI. Dependence of carrier temperature on chemical purity

Autor: J W Hodby, U Gross, G T Jenkin

Publikováno v: Journal of Physics C: Solid State Physics. 4:L89-L91

The first direct measurement by cyclotron resonance of the mass of the cold polaron in KI has been made using a zone-refined specimen. In specimens of lower purity, photoexcited carriers do not cool to the temperature of the lattice.

The Use Of Cd0.7Hg0.3Te Grown On GaAs For Optical Fibre Communication Devices

Autor: John Thompson, L M. Smith, T N. Duy, P. Gori, G T. Jenkin

Publikováno v: SPIE Proceedings.

Cd0,7Hg0.3Te has been grown by MOCVD on GaAs in part of an optical fibre communication device study. Auto-doping from the substrate is contained in a suitable buffer layer and a thin HgTe layer has been used as the p-type contact. Preliminary device

MOCVD of CMT

Autor: M. J. Hyliands, G. T. Jenkin, J. Thompson, K. T. Woodhouse, V. Vincent

Publikováno v: SPIE Proceedings.

Avalanche photodiodes (APD) based on bulk grown Cd0.7Hg0.3Te ( λ = 1.55 µm) offer significant advantages over the diodes fabricated from group III-V and group IV semiconductors. Metal Organic Chemical Vapour Deposition (MOCVD) is a well established
