Tungsten (also called wolfram) [14] [15] is a chemical element; ... In electronics, tungsten is used as an interconnect material in integrated circuits, ...
An active or passive element of an electronic circuit. electronic control unit In an automobile, an embedded electronic system that controls some aspect of a vehicle (ignition, transmission, and so on). electronic design automation A system in which a computer provides assistance to the designer of a device or system. electronic engineering
By coating the tungsten with a substance of lower work function (e.g., thorium or barium oxide), the emission can be greatly increased. This prolongs the lifetime of the filament by allowing operation at lower temperatures (for more information, see hot cathode). Band bending models in solid-state electronics
A halogen lamp (also called tungsten halogen, quartz-halogen, and quartz iodine lamp) is an incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine.
While tungsten-carbide bits are very hard, they eventually wear out or break. Drilling is a considerable part of the cost of a through-hole printed circuit board. Surface mount components, including resistors, transistors and an integrated circuit A PCB in a computer mouse: the component side (left) and the printed side (right)
The various metal layers are interconnected by etching holes (called "vias") in the insulating material and then depositing tungsten in them with a CVD technique using tungsten hexafluoride; this approach can still be (and often is) used in the fabrication of many memory chips such as dynamic random-access memory (DRAM), because the number of ...
The carrier density is important for semiconductors, where it is an important quantity for the process of chemical doping.Using band theory, the electron density, is number of electrons per unit volume in the conduction band.
By careful treatment, extremely thin wire can be produced. Special purpose wire is however made from other metals (e.g. tungsten wire for light bulb and vacuum tube filaments, because of its high melting temperature). Copper wires are also plated with other metals, such as tin, nickel, and silver to handle different temperatures, provide ...
