Germanium

grab it but before you do a person named Clemens Winkler grabs it first. Later becomes famous for discovering germanium and all that. Pretty boring right. Well that’s what this essay is about. It’s pretty boring, not going to lie, so will you just stay with me?This first part of me telling you about germanium is going to have a lot of numbers and will most likely be boring. Anyway, Germanium is a gray-white element that was found in a silver mine in Freiberg, Germany. It was found by Clemens Winkler

) Description of the HPGe gamma-ray spectrometer A high resolution gamma detection system was used for gamma analysis. This system consist of an ORTEC hyper pure germanium detector (HPGe), model number GEM- 15190, coaxial type detector with a serial number 27-P-1876A recommended operating bias, negative 3 Kv. The detector used has crystal diameter 49.3 mm, and crystal length 47.1 mm. The HPGe detector has a full width at half maximum (FWHM) 0.9 keV at the 122 keV gamma transition of Co-57 and 1.9

The figure 1 gives a brief description of the 3-D FinFET structures which have been simulated. According to the International Technology Roadmap for Semiconductors (ITRS), The gate length (Lgate) is 15 nm, which corresponds to the 7/8-nm technology having 0.64 nm as gate- oxide thickness. The height (HSi) and width of fin (WSi) are 40nm and 8nm respectively whereas the the fin pitch is 30 nm and the fin aspect ratio is 5 which are taken from the characteristics of Intel 22-nm [1] and 14-nm FinFET

Solar Cell Degradation in Space Abstract: This paper will present the degradation of solar cell performance when exposed to solar wind in space, particularly in the Van Allen belt region. Also, solar cell theory is mathematically modeled and described using Matlab simulation software accompanied by the SRIM software to generate the targeting data. Follow with the degradation modeling of Si, InGaP/GaAs/Ge triple-junction space solar cells when are exposed to high energy charged particles, especially

Chemistry and technology has allowed so many advancements in today’s society. It has allowed us to have faster computers, better displays, bigger hard disks(hard drives),and it gives us the ability to work, to create, and to play. The main focus point of my research is how chemistry has advanced computers with the work of transistors. A transistor is a semiconductor device that can amplify, control and generate electrical signals. Transistors look like integrated circuts. They are placed in micro

The earth intercepts over 173 thousand terawatts of energy. Solar cells offer a means to harness this energy by converting solar energy into electrical energy. While some may argue that solar energy is an inconsistent energy source, research is being poured into creating more efficient solar cells so that when light is incident on the solar cell, the solar cells operate at their highest possible efficiency levels. Currently, the most efficient solar cells convert 34.5% of sunlight to energy. With

existence of another row to the table which were the actinides which were some of the heaviest in atomic mass. Some people dismissed Mendeleev for predicting that there would be more elements, but he was proved to be correct when Ga (gallium) and Ge (germanium) were found in 1875 and 1886 respectively, fitting perfectly into the two missing spaces. Later on in life, he created the periodic table. By giving Sanskrit names to his "missing" elements, Mendeleev showed his appreciation and debt to the Sanskrit

Today we will be talking about two very important elements, one of them is called Silicon. The other is called germanium. These elements are important because without them, you wouldn’t be able to do most of the things that you consider “fun”. So I would first like to start off talking about Germanium and then finish off by talking about Silicon. So here we go. Germanium is a solid element that looks similar to silicon. It has a grayish color to it and has a glittery look to it. Its atomic number

Germanium weighs 72.61lbs, and the boiling point is 2830 degree Celsius. In addition, germanium has 9 isotopes, and the atomic mass i 72.59. However, “the element germanium is both metals and nonmetals. To be more precise, germanium is a very important element that light and shiny. Firstly, germanium is “hard, lustrous, gray-white, brittle metalloid. It has a diamond like crystalline structure and it is similar in chemical and physical properties to silicon”. Secondly, germanium was discovered by

Jars of Red Germanium In all the years since Maycomb was first established, many different changes had occurred, but the one place that remained the same, was the cemetery. The place had a gloomy and dilapidated feel to it, nobody had the money to fix it, and nobody had the will to do it. The bushes were overgrown and weeds spewed out from cracks in the pavement. On the day of Bob’s funeral, the sun was hidden from us behind the curtain of grey clouds. We were never tempted to venture near the cemetery
