to the formation of silicon carbide (SiC). And also graphite…

Within a photovoltaic cell, there are two pieces of silicon; type P (positive charge) and type N (negative charge). When put together, an electromagnetic field is created due to the attraction between them and free electrons are attracted to the opposing side (positive or negative). As the charges build up it becomes difficult for any electrons to cross. At the moment light makes contact with the upper layer of silicon, those electrons are forced by the electromagnetic field into a current…

It modifies the electrical properties of substances such as silicon and germanium. Another benefit of boron for our modern technology is its use in neodymium magnets. These powerful magnets are an alloy of neodymium, iron and bron. The magnets used are found in computers, specifically hard drives. E-waste, short…

are leaving villagers in China to grapple with the toxic effects of silicon production. Green energy companies in China, such as the Luoyang Zhonggui High-Technology Co., produce polysilicon destined for solar energy panels to be sold around the world. The byproduct of polysilicon production is silicon tetrachloride which poses environmental hazards (Cha, 2008). For each ton of polysilicon produced, at least four tons of silicon tetrachloride liquid waste is generated (Cha, 2008). This compound…

contrast from Santa Clara’s safe and happy environment. Three things stood out in my mind from my first visit to the Greater Washington Community. The first problem is the gang violence. The second is prostitution. To this day I am still appalled that Silicon Valley, with its billions of dollars in assets are unable to solve issues such these. My perception of the community has not changed, but instead has only been made even clear. Before the visit to the community, I did not know anyone who…

the characteristics of an unknown were similar to a certain column of elements we would place the unknown element in the column. Unknown element number 8 is silicon because of its matching characteristics with the other elements in the group. Silicon was alike with the other elements by the colors and density they all had. The only place silicon belongs is column 14 it is a dark grey element with a metallic luster. Elements in the same column are a dark grey close to black unlike the rest of the…

The current standard for the kilogram is the International Prototype Kilogram. The International Prototype Kilogram, also known as Le Grand K, is a platinum-iridium bar made in the 1880’s. This official Kilogram is kept in a vault in Paris under two glass domes. The reason it is under 2 glass domes it to prevent dust from obstructing from the weight of the Kilogram. However according to Sandia National Laboratories, a government organization under the Department of Energy, “Of the seven units of…

Job Offer Negotiations Joe Tech is a recent MBA graduate negotiating the job offer for his first permanent position. The position offered is with a leading technology company in Silicon Valley, Robust Routers, for which Joe was an intern the prior summer. He performed well during the internship and his manager, Leigh Bultema, offered him a permanent position. The offer was for the Associate Produce Manager position in the Terabit Router Group and included the following: The offer was made…

Solar Energy Energy is considered as the most important issue of the 21st century. About 85% of today’s modern world use of energy comes from fossil fuels (Blah Blah). These particular resources, fossil fuels, are finite in quantity, and has been a major cause of air pollution and global warming. Scientists are finding alternative sources of energy to solve the century’s puzzle, a resource which is renewable, natural and efficient such as solar energy. Over 2700 years ago, people have been…

solar panels generally consist of silicon and various conductive materials to transfer the electricity into a home or building. In this concept we can use other materials in addition to silicon as the primary component that absorbs UV light from the Sun's rays. This will increase the efficiency while only increasing the cost by a small margin. The cost to yield ratio for solar panels working in Tandem with silicon is much higher than with only one material. Silicon is used as the base material…
