Semiconductor

On the SSA 3369 in the current file she listed this job as “Floater” for national semiconductor. The job is adequately described to determine she cannot perform the job as actually performed. She describes her job as assembling wafers, placed them in machines, lifted boxes of wafers, put wafers in acid or solvent to clean them, did paperwork…

Growing up I never really had a problem when it came to learning. It did not matter what the subject was, I always found a way to learn it. You know at that time of my life, caring about ‘how’ I learned was of no care to me just as long as I received no less than high B as my grade. I recently taken a self-assessment to see what my primary learning style is and the results were unsurprising. At 30% auditory, 35% visual, and 35% for tactile, the self-assessment reveals that I am a…

3.2 Performance The first thing to consider when talking about a light bulb’s performance is the brightness. The brightness of a light bulb is measure in lumens (lm). It measures how much light the bulb outputs so the more lumens, the brighter the light. The power consumption is also important to know how many lumens a bulb produces per watt. The ratio of total output lumens per total watts used to power a light bulb is called luminous efficacy. Figure 2 shows a table comparing the luminous…

PV (photovoltaic) solar panels get their energy from sunlight, using nothing more than a property of physics (the photovoltaic property) and sheets of semiconductors (SEIA). Energy from the sun excites electrons and causes them to “free themselves” and run through a circuit, powering electronic devices along their way (SEIA). Wind energy is generated in a close fashion to how fossil fuel power plants gather…

CPU known as Central Processing Unit also referred as Processor, Central Processor or microprocessor of the computer. It handles all the instructions from Hardware and Software. It is also called the brain of a computer as all the information is saved and stored in it. The CPU was first developed at Intel and they released 4004 processor. CPU chips are used in digital computers and often used to do the calculations. Processor is the engine of a computer; from this we can tell how fast the system…

talks about is element 75 - Rhenium (R, which was also one of Mendeleev's predictions. Noddack, Tacke and Berg all contributed in the discovery of this element, as well as the founded research Rhenium is used for parts in jet engines, making of semiconductors , nuclear reactors, electronic tube components, and more. The fourth element he talks…

essential information on solar energy, that once understood, helps to answer whether solar panels are energy efficient. First, what is it that encompasses a solar panel? Solar panels are made up of solar cells. A solar cell is a small portion of a semiconductor, which is made to reflect as little light as possible. Depending on the material used to make the solar cell, the overall…

Review of Literature You get solar energy only through direct sunlight. It is the most abundant, pure, non-toxic renewable energy source. There is sunlight every day that shines down on the earth that is 100,000 times greater than the whole world’s power capacity. The sun has always been a potential source of energy, but it wasn’t until the extreme cost rise of conventional energy that people finally took an interest. After more complex ways to use solar energy were discovered, more and more…

much smaller and consumes a lot less power compare to the vacuum tube. University of Manchester created the first transistorize computer in 1953, and by 1955, the computer had only 200 transistors and consumed 150 watts. Then the discovery of the semiconductor silicone took the transistor to the next level; thousands or millions of transistor can be pack on to a tiny chip, and as a result, the computer processing power increase exponentially by the year. In 1970, the Moore’s law states that the…

Significance of IQHE References Introduction The integral quantum hall effect (IQHE) was first discovered by Klaus von Klitzing and coworkers in 1980. It was demonstrated by two dimensional electron system in a device called metal oxide semiconductor field effect transistor (MOSFET), under low temperature and large magnetic field. They discovered that the transverse conductance dropped to zero at some values of magnetic field, and concurrently the longitudinal resistance didn’t…
