Photoconductivity in Oxygen Deficient La0.7 Pbx □0.3 − x MnO3 − δ Thin Films Prepared by Chemical Route

We report the influence of light irradiation on the electrical properties of oxygen deficient La_0.7Pb_x □_{0.3 − x} MnO_{3 − δ} thin films with (x = 0.1) and without (x = 0.3) cation vacancies (noted by □). Transient ph...

Can soft X-ray spectra of AGN be taken as emission from accretion disks?

Soft X-ray spectra of many Active Galactic Nuclei (AGN) show structure which suggest excess emission at low energies, mostly below 1 keV. This component may be the high energy tail of the so called blue bump w...

Microoptical Components and Systems Fabricated by the LIGA Process

In microsystem technology the LIGA technique is well established for the fabrication of microstructures. By use of the combination of deep-etch X-ray lithography with synchrotron radiation, electroforming and ...

Infrared Observation of Non Thermal Emissions from Spacelab

Observations of the emissions of atmospheric ozone and nitric acid in the 10 μm window have already been used for the monitoring of these constituents in the stratosphere. We propose to generalise these method...
