“…The broadening at the edge of the electrodes is smaller than the size of the scanning step (10 mm). As observed in our previous work (Ciancaglioni et al, 2011), where a similar detector with multi-strip structures was tested under a microfocused X-ray beam, a strip broadening of 4 mm was measured, very close to the intrinsic size of the microfocused X-ray beam (about 3 mm). Based on this observation it might be possible to achieve a position sensi-tivity of the order of 1 mm by decreasing the gap separating the electrodes.…”

(2012 A novel beam position monitor, operated at zero bias voltage, based on highquality chemical-vapor-deposition single-crystal Schottky diamond for use under intense synchrotron X-ray beams was fabricated and tested. The total thickness of the diamond thin-film beam monitor is about 60 mm. The diamond beam monitor was inserted in the B16 beamline of the Diamond Light Source synchrotron in Harwell (UK). The device was characterized under monochromatic high-flux X-ray beams from 6 to 20 keV and a micro-focused 10 keV beam with a spot size of approximately 2 mm Â 3 mm square. Time response, linearity and position sensitivity were investigated. Device response uniformity was measured by a raster scan of the diamond surface with the micro-focused beam. Transmissivity and spectral responsivity versus beam energy were also measured, showing excellent performance of the new thin-film single-crystal diamond beam monitor.

Photoelectric detectors are the central part of modern photodetection systems with numerous commercial and scientific applications. p-Type semiconductor materials play important roles in optoelectronic devices. Photodetectors based on p-type semiconductor materials have attracted a great deal of attention in recent years because of their unique properties. Here, a comprehensive summary of the recent progress mainly on photodetectors based on inorganic p-type semiconductor materials is presented. Various structures, including photoconductors, phototransistors, homojunctions, heterojunctions, p-i-n junctions, and metal-semiconductor junctions of photodetectors based on inorganic p-type semiconductor materials, are discussed and summarized. Perspectives and an outlook, highlighting the promising future directions of this research field, are also given.

Diamond is not an unfamiliar material for most people as it is being widely used in jewelry over the past several centuries. Besides being metastable and having a shiny appearance, diamond has the highest mineral hardness and thermal conductivity among natural materials while posessesing extraordinary properties among ultra-wide bandgap semiconductors. Compared with traditional semiconductors, such as Si, GaAs, SiC, and so on, diamond has superior carrier mobility, good optical transparency, and high radiation hardness. As a result, radiation detector applications in high-energy physics experiments began to exploit natural diamond materials from as early as in the middle of the last century. However, the highly variable and uncontrollable defect content and concentration of impurities in natural diamonds constrain the advanced and reliable application of diamond electronic devices. In recent years, the development of diamond synthesis techniques via chemical vapor deposition (CVD) has led to investigations into diamond electronic applications, as large-area (centimeter scale) production of single-crystal diamond can be realized, and the impurity concentration can be controlled. Diamond radiation detectors therefore represent one of the research projects that underwent some decades of investigation and are still being under study. In this chapter, we summarize the detection mechanisms in two different types of diamond detectors: 1) diamond photoconductors and 2) Schottky barrier photodiodes, which depend strongly on the contact properties between the electrode materials and diamond surface. Meanwhile, the main features of diamond detectors, like responsivity, quantum efficiency, charge collection efficiency, charge collection distance, and others, are introduced and discussed. The remarkable properties of diamond promise several opportunities in a diverse range of application fields, whereas the daunting technical challenges, such as relating to size, doping, and manufacturing scalability, are still in the way of high technology commercialization, especially in electronics. Nevertheless, with new developments in materials synthesis, and research and practical applications, the outlook for diamond is exciting.
