Experimental performances and Monte Carlo modelling of LWIR HgCdTe avalanche photodiodes
We report the performances of LWIR (λc = 9.0 μm at 80K) HgCdTe electron injected avalanche photodiodes (e-APD). In these devices, the exponential gain curve, up to gains equal to 23 at 100K, and the low excess noise factor close to unity (F ~ 1-1.25) are indicative of a single carrier multiplication process, which is electron impact ionization. The dark current is mainly due to a diffusion curr...

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...
15 صفحه اولAnalysis 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...
متن کاملReliability Modeling of a Manufacturing Cell Operated under Degraded Mode
In this study, a stochastic model is developed to analyze performance measures of a manufacturing cell, which is allowed to operate under degraded mode. The model is used to determine reliability and productivity of the cell, as well as the utilization of its components, under various operational conditions, including equipment failures and fault-tolerant states. The model and the results can b...
متن کاملHigh performance InP Geiger-mode SWIR avalanche photodiodes
LAser Detection And Ranging (LADAR) is a promising tool for precise 3D-imaging, which enables field surveillance and target identification under low-light-level conditions in many military applications. For the time resolution and sensitivity requirements of LADAR applications, InGaAsP/InP Geiger-mode (GM) avalanche photodiodes (APDs) excel in the spectrum band between 1.0~1.6 μm. Previously MI...
