chemistry is used in many ways in computers also.for example.‚we use many elements like silicon‚zinc‚aluminium‚copper etc.‚. in designing and in developing the hardware of computer. Electronics: Chemistry is important in many electronics fabrication and packaging methods and may one day help extend the trend toward faster and cheaper electronics by \molecular electronics‚" where individual molecules are used as electronic components. Chemists have always played a fundamental role in the

vice versa The microelectronics industry is continually striving to miniaturize conventional silicon-based electronic devices to provide higher performance technology that can be housed in smaller packaging. Progress resulting from this miniaturization is evident from the rapid advances in consumer electronics‚ such as cell phones and laptop computers‚ that have been observed in recent years. Now‚ silicon-based molecular electronics -- a complementary technology to conventional microelectronics that

Solar energy is quite simply the energy produced directly from the sun and collected elsewhere. All solar cells are made of silicon. Thin- Film Photovoltaic technology directly converts solar energy into electricity. Solar cells are made out of semiconducting material‚ usually silicon. The process of making a solar cell begins with taking a slice of highly purified silicon crystal‚ and then processing it through several stages involving gradual heating and cooling. Solar cells are based on semiconductor

intrinsic silicon with a carrier mobility of 1500 cm2/V-1s-1‚ we can see that graphene is not only better but it overpasses silicon’s carrier mobility by 133 times11. It is clear that graphene can be a good candidate to replace silicon in the electronics industry. For example‚ Intel Corporation now sells chips with 32nm size transistors and even six cores on a single microprocessor with a value of $1000. In other words‚ consumers are paying high amounts of money to buy a tiny piece of silicon. It is

Semiconductor materials Silicon is the most commonly used semiconductor in electronics‚ germanium is also used. These elements form a stable crystal lattice‚ with each atom sharing its four outer electrons (called valence electrons) with neighbouring atoms. Silicon is a poor conductor because the outer electrons in each atom are held firmly in place by the crystalline structure. Doping Doping
