Silicon | Si - PubChem

Silicon (Si) is a light chemical element that coines with oxygen and other elements to form silies. Silicon in the form of silies constitutes more than 25% of the Earth''s crust. Silica (SiO2) as quartz or quartzite is used to produce silicon ferroalloys and silicon metal. metal.

Diode - Simple English Wikipedia, the free encyclopedia

A diode is an electronic component with two electrodes (connectors) that allows electricity to go through it in one direction and not the other direction. Diodes can be used to turn alternating current into direct current (Diode bridge). They are used in power supplies and sometimes to decode amplitude modulation radio signals (like in a

Kiürített tartomány – Wikipédia

A félvezetők fizikájában a kiürített tartomány, más nevén kiürített réteg egy dópolt félvezető anyag belsejében létrejövő szigetelő tulajdonságú réteget jelent, melyből a szabad töltéshordozók diffúzió vagy elektromos mező hatására távoztak.A ''kiürített tartomány'' elnevezés azon alapul, hogy egy elektromos áram vezetésére képes anyagban a szabad

Remeer type-ins? - The Silicon Underground

An article on type-in programs just showed up on Wikipedia. Ah, memories. There was a time when the programs listed in the back of a magazine were at least as important as the editorial content.I mentioned to the initial author of the article that type-ins became a bit of a bragging right.

Properties of Silicon

A p-type (positive-type) extrinsic silicon semiconductor is a semiconducting material that was produced by doping silicon with an p-type element of group III A, such as B, Al, or Ga. Since the dopants are acceptor atoms, holes are the majority charge carriers of the material.

Silicon Valley may look geeky and anodyne on the outside, with its Priuses and half-zip sweaters and eggheaded stars, but it has a far more sinister and prurient side—that may

Polycrystalline Silicon | AMERICAN ELEMENTS

Silicon-based photovoltaic cells (PV Cells) for solar energy are fabried from a positively charged or p-type silicon layer underneath a negatively charged or n-type silicon layer. These layers can be produced from casted polycrystalline material sold under the AE Solar Energy group.

Lead - Simple English Wikipedia, the free encyclopedia

Lead (pronounce: "/''lɛd/") is a chemical element. Its chemical syol is Pb, which comes from pluum, the Latin word for lead.[3] Its atomic nuer is 82, atomic mass is 207.2 and has a melting point of 327.8°C. It is a very poisonous and heavy metal.
