Investigations into the source of 1/f noise in HgxCd1−xTe diodes

Autor: C. T. Elliott, Neil Gordon, C. D. Maxey, L. G. Hipwood, C. L. Jones, R. A. Catchpole, M. K. Ashby

Publikováno v: Scopus-Elsevier

This work is aimed at elucidating the mechanism of 1/f noise in HgxCd1−xTe diodes in order to reduce 1/f noise in high-performance thermal cameras. Currently, to reach the required signal-to-noise ratio, the operating temperature of thermal cameras

Infrared negative luminescent devices and higher operating temperature detectors

Autor: Geoffrey R. Nash, David J. Hall, Janet E. Hails, G. Masterton, Jean Giess, M. T. Emeny, Neil Gordon, M. K. Ashby, Timothy Ashley, L. Haworth, J.C. Little

Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 20:540-547

Infrared LEDs and negative luminescent devices, where less light is emitted than in equilibrium, have been attracting an increasing amount of interest recently. They have a variety of applications, including as a ‘source’ of IR radiation for gas

Long wavelength infrared negative luminescent devices with strong Auger suppression

Autor: Neil Gordon, James R. Lindle, M. K. Ashby, Jean Giess, Jerry R. Meyer, L. Haworth, Timothy Ashley, Geoffrey R. Nash, William W. Bewley

Publikováno v: Journal of Applied Physics. 94:7300-7304

We have investigated the negative luminescent properties of HgCdTe photodiodes having peak emission at a wavelength of 7.6 μm, as a function of temperature and applied bias. Under reverse bias at room temperature, intrinsic Auger processes are almos

Novel HgxCd1−xTe device structure for higher operating temperature detectors

Autor: Neil Gordon, C. T. Elliott, R. A. Catchpole, L. G. Hipwood, C. D. Maxey, C. L. Jones, M. K. Ashby

Publikováno v: Journal of Electronic Materials. 32:667-671

A novel detector structure in which photons are absorbed in narrow-gap material, but the junction lies in wider bandgap material, has been examined. A possible reduction in bulk 1/f noise by a factor of 33 for a 240 K operation was predicted, based o

DNA sequencing and complementation/deletion analysis of the bchA-puf operon region of Rhodobacter sphaeroides: in vivo mapping of the oxygen-regulated puf promoter

Autor: J. G. Burgess, C. N. Hunter, M. K. Ashby, Peter McGlynn, John D. Olsen

Publikováno v: Scopus-Elsevier

Within the photosynthetic gene cluster of Rhodobacter sphaeroides the genes encoding light-harvesting LHI and reaction-centre complexes are transcriptionally linked in the order pufBALMX. The region stretching 1.6 kb upstream of pufB has been examine

Analysis of multiple copies of geminiviral DNA in the genome of four closely related Nicotiana species suggest a unique integration event

Autor: M K, Ashby, A, Warry, E R, Bejarano, A, Khashoggi, M, Burrell, C P, Lichtenstein

Publikováno v: Plant molecular biology. 35(3)

Previously, we discovered multiple direct repeats of geminivirus-related DNA (GRD) sequences clustered at a single chromosomal position in Nicotiana tabacum (tobacco). Here we show that, in addition to tobacco, multiple copies of these elements occur

Characterization and complementation of a mutant of Rhodobacter sphaeroides with a chromosomal deletion in the light-harvesting (LH2) genes

Autor: Burgess Jg, C. N. Hunter, M. K. Ashby

Publikováno v: Journal of general microbiology. 135(7)

SUMMARY: An LH2- strain of Rhodobacter sphaeroides, DBC1, has been constructed by deleting the puc operon, which encodes the LH2 α and β polypeptides, from the chromosome and replacing it with a kanamycin resistance gene. Southern blot analysis ind
