Silicon Photomultipliers (SiPM) are very promising new types of photon detectors. They are based on a matrix of many independent pixels (typically 400 or 1600 pixels for a 1x1 mm 2 device). Each pixel is an avalanche photodiode (APD) working in limited Geiger mode at a low bias voltage ...
The Czochralski Method:A small seed crystal of silicon is dipped into a molten silicon melt. As the seed crystal is slowly pulled upwards and rotated, it initiates the growth of a single crystal of silicon. The controlled cooling of the crystal further refines its structure, yielding a large...
To improve the drawbacks caused by the sludge ash replacement in mortar, the previous studies have shown that the early strength and durability of sludge ash/cement mortar are improved by adding nano-silicon dioxide (nano-SiO2) to mortar. In this article, three types of nano-SiO2—SS, HS, ...
The effects of different types of nano-silicon dioxide additives on the prop-erties of sludge ash mortar. Luo Huan-Lin,Chang Wei-Che,Lin Deng-Fong. Journal of the Air&Waste Management Association . 2009Luo Huan-Lin, Chang Wei-Che, Lin Deng-Fong. The effects of different types of nano ...
The devices have been fabricated on SOI wafers with a 3 μm-thick silicon layer. In all cases, the quality factors of the resonances of a given resonator have been found to significantly change form peak to peak. This can be attributed to wavelength dependent losses in the feedback ...

like in 6061, you will find magnesium and silicon traces inside Aluminum 6063 alloys (you may even find traces of iron, copper, or zinc in minimal percentage amounts). 6063’s properties allow it to be very easily extruded, and because of that, it is one of the most common metals used...
What are silicon & thin film capacitors? Figure 21: Silicon & thin film capacitors in various package formats. (Not to scale) Device construction and distinguishing traits Silicon and thin film capacitors are a relatively new crop of devices produced using tools, methods, and materials borrowed fr...
1)Table Salt : Once of the most widely used salts, table salt goes through a refining process that removes traces of other naturally occurring minerals. Chemical additives such as sodium silicon-aluminate, calcium phosphate, or magnesium carbonate are sometimes blended in to prevent ...
The term SCR stands for silicon controlled rectifier which is one of the most important members of the thyristor family. It is more popular than the other Thyristors like TRIAC, SCS, DIAC, etc
