375GM-bandwidth photoconductive detector
Much progress has been made over the past several years in the development of high-speed photodiode detectors. A detection bandwidth of 105 GHz together with a responsivity of 0.1 A# have been reported for a metalsemiconductor-metal (MSM) photodiode.’ The most common approach to increasing the bandwidth in MSM photodiodes (at least up to 100 GHz) is to shorten the carrier transit time by reduci...
متن کاملSynthetic diamond-based position-sensitive photoconductive detector development for the Advanced Photon Source.
A novel X-ray beam-position detection device that we call a position-sensitive photoconductive detector (PSPCD) is designed to have synthetic diamond as its substrate material. We proved that it is feasible to use synthetic diamond to make a hard X-ray position-sensitive detector based on the photoconductivity principle and that it acts as a solid-state ion chamber. Experiments on different PSP...
متن کاملA Broadband THz-TDS System Based on DSTMS Emitter and LTG InGaAs/InAlAs Photoconductive Antenna Detector
We demonstrate a 4-f terahertz time-domain spectroscopy (THz-TDS) system using an organic crystal DSTMS as the THz emitter and a low temperature grown (LTG) InGaAs/InAlAs photoconductive antenna as the receiver. The system covers a frequency range from 0.2 up to 8 THz. The influences of the pump laser power, the probe laser power and the azimuthal angle of the DSTMS crystal on the time-domain T...
متن کاملCvd-diamond-based Position Sensitive Photoconductive Detector for High-flux X-rays and Gamma Rays
A position-sensitive photoconductive detector (PSPCD) using insulating-type CVD diamond as its substrate material has been developed at the Advanced Photon Source (APS). Several different configurations, including a quadrant pattern for a x-ray-transmitting beam position monitor (TBPM) and 1-D and 2-D arrays for PSPCD beam profilers, have been developed. Tests on different PSPCD devices with hi...
متن کاملAnalysis of Crosstalk in HgCdTe based Vertical Photoconductive LWIR Detector Arrays
HgCdTe is a well known material for Infrared detection applications because of its special properties like high absorption coefficient, adjustable bandgap and moderate dielectric constant etc. Vertical PC detectors of HgCdTe are very easy to fabricate as compared to the other detectors with the desired uniformity and therefore, these detectors may be proved better choice if the cost and the yie...
