X-ray induced photocurrent characteristics of CVD diamond detectors with different carbon electrodes
Diamond has unique properties which make it suitable for a broad range of radiation detection applications ranging from particle timing and spectroscopy, to neutron, UV and X-ray sensors. In X-ray dosimetry, the atomic number of diamond (Z = 6) close to that of the human tissues (Z = 7.42) allows to mimic the real absorbed dose avoiding off-line recalculations. Moreover, its low atomic number a...
متن کاملStructural and Mechanical Properties of Diamond-like Carbon Films Prepared by Pulsed Laser Deposition with Varying Laser Intensity
Diamond-like carbon (DLC) films have been prepared by pulsed laser deposition (PLD) (wavelength 248 nm), ablating highly oriented pyrolytic graphite (HOPG) at room temperature in a vacuum of 10.2 Pa, at fluences between 0.5 and 35 Jcm. Films have been deposited on Si(100) with and without a SiC interlayer. Structural analysis, such as visible and UV Raman, Infrared and Electron Energy Loss (EEL...
متن کاملDeposition of fine carbon particles using pulsed ArF laser ablation assisted by inductively coupled plasma
Carbon thin films containing many fine carbon particles were deposited by a pulsed ArF laser ablation technique assisted by inductively coupled plasma (ICP). The sizes of the particles were found to be ~ 100 nm. The particles seemed to be coagulated from several finer particles of size ~ 10 nm. When ICP was applied to a plume, the shape of the coagulated particles became spherical. The deposite...
متن کاملPulsed Laser Deposition of Diamond-like Carbon Thin Films: Ablation Dynamics and Growth
Thin films of diamond-like carbon have been grown by pulsed laser deposition using a Nd:YAG laser at 532 nm. Time-of-flight mass spectroscopy was used to investigate the effects of laser power density and background gas pressure on the plume characteristics including the species in the plume and the kinetic energy distribution of each species. We found that with increasing laser power density (...
متن کاملWavefront control of UV narrow bandpass filters prepared by plasma ion-assisted deposition
Metal oxide layers produced by plasma ion-assisted deposition are extensively used for complex optical coatings due to the availability of materials, the high packing density of films, and the smooth surfaces. Stringent optical surface figure specifications necessary for both laser optics and precision optics require film stress to be well controlled and surface deformation to be corrected or c...
