semiconductor sem·i·con·duc·tor. n. 1. Any of various solid crystalline substances, such as germanium or silicon, having electrical conductivity greater than insulators but less than good conductors, and used especially as a base material for computer chips and other electronic devices. 2.ny of various solid substances, such as silicon or germanium, that conduct electricity more easily than insulators but less easily than conductors. Semiconductors are able to do this because they have a small number of electrons that have escaped from the bonds between the atoms, leaving open spaces.

Period 6 element Caesium is an alkali metal and has physical and chemical properties similar to those of rubidium and potassium. The metal is extremely reactive and pyrophoric, reacting with water even at −116 °C (−177 °F). Caesium is one of the most reactive elements of all, even more reactive than fluorine, the most reactive nonmetal.

- Cadmium (Cd, atomic number 48) is a silver-or bluish-white metal in the group 12 of the periodic table. It is usually found with an oxidation state of +2 and combined with other elements such as oxygen (cadmium oxide), chlorine (cadmium chloride), or sulfur (cadmium sulfate, cadmium sulfide).ccording to a study by the Associated Press (AP) cadmium emerged as a safety concern after AP’s investigation revealed that lab tests conducted on 103 pieces of low-priced children’s jewelry found 12 items with cadmium content above 10 percent of the total weight.

What Is Thorium? Thorium is a radioactive chemical element found in nature as thorium-232. It is found primarily in the rare earth mineral monazite but can also be found in euxenite and thorianite. Thorium is found more abundantly in the Earth’s crust than uranium and only occurs naturally in an oxidized form. Pure thorium is soft, very ductile and has a lustrous silvery-white appearance.

- Indium is a soft, malleable metal with a brilliant lustre. The name indium originates from the indigo blue it shows in a spectroscope. Indium has a low melting point for metals and above its melting point it ignites burning with a violet flame. Bizarrely, the pure metal of indium is described as giving a high-pitched cry when bent.

SILICON Silicon is a metalloid, one of only a very few elements that have characteristics of both metals and non-metals. Silicon is the second most abundant element in the Earth's crust, exceeded only by oxygen. Many rocks and minerals contain silicon.Examples include sand, quartz, clays, flint, amethyst, opal, mica, feldspar, garnet, tourmaline, asbestos, talc, zircon, emerald, and aquamarine.Silicon never occurs as a free element.ilicon never occurs as a free element in nature. It always occurs as a compound with oxygen, magnesium, calcium, phosphorus, or other elements. The most common minerals are those that contain silicon dioxide in one form or another.

Semiconductor device By far, silicon (Si) is the most widely used material in semiconductor devices. Its combination of low raw material cost, relatively simple processing, and a useful temperature range makes it currently the best compromise among the various competing materials.ermanium (Ge) was a widely used early semiconductor material but its thermal sensitivity makes it less useful than silicon. Today, germanium is often alloyed with silicon for use in very-high-speed SiGe devices; IBM is a major producer of such devices.

Period 3 element Silicon is a chemical element with symbol Si and atomic number 14. It is a tetravalent metalloid, more reactive than germanium, the metalloid directly below it in the table.Controversy about silicon's character dates to its discovery; it was first prepared and characterized in pure form in 1823.lthough most free silicon is used in the steel refining, aluminium-casting, and fine chemical industries (often to make fumed silica integrated circuits, the basis of most computers, a great deal of modern technology depends on it.

- Silicon dioxide, also known as silica (from the Latin silex), is a chemical compound that is an oxide of silicon with the chemical formula Si O 2. It has been known since ancient times.Silica is most commonly found in nature as quartz, as well as in various living organisms.he solubility of silicon dioxide in water strongly depends on its crystalline form and is 3–4 times higher for silica than quartz; as a function of temperature, it peaks at about 340 °C.

Ribose Ribose is an organic compound with the formula C 5 H 10 O 5; specifically, a pentose monosaccharide (simple sugar) with linear form H−(C=O)−(CHOH) 4 −H, which has all the hydroxyl groups on the same side in the Fischer projection.The term may refer to either of two enantiomers.The term usually indicates D-ribose, which occurs widely in nature and is discussed here. Its synthetic mirror image, L-ribose, is not found in nature. -Ribose was first reported in 1891 by Emil Fischer.t is a C'-2 carbon epimer of the sugar. - arabinose (both isomers of which are named for their source, gum arabic) and ribose itself is named as a transposition of the name of arabinose. The ribose β-D-ribofuranose forms part of the backbone of RNA.
