  2. Insulated-gate bipolar transistor - Wikipedia

    en.wikipedia.org/wiki/Insulated-gate_bipolar...

    Invented. 1959. Electronic symbol. IGBT schematic symbol. An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily forming an electronic switch. It was developed to combine high efficiency with fast switching. It consists of four alternating layers (NPNP) [1][2][3][4][5] that are controlled by a metal ...

  3. Linear energy transfer - Wikipedia

    en.wikipedia.org/wiki/Linear_energy_transfer

    Linear energy transfer. Diffusion cloud chamber with tracks of ionizing radiation (alpha particles) that are made visible as strings of droplets. In dosimetry, linear energy transfer (LET) is the amount of energy that an ionizing particle transfers to the material traversed per unit distance. It describes the action of radiation into matter.

  4. TNT equivalent - Wikipedia

    en.wikipedia.org/wiki/TNT_equivalent

    TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.

  5. Charge transport mechanisms - Wikipedia

    en.wikipedia.org/wiki/Charge_transport_mechanisms

    Characterization of transport properties requires fabricating a device and measuring its current-voltage characteristics. Devices for transport studies are typically fabricated by thin film deposition or break junctions. The dominant transport mechanism in a measured device can be determined by differential conductance analysis.

  6. Gigabit Ethernet - Wikipedia

    en.wikipedia.org/wiki/Gigabit_Ethernet

    For the camera protocol, see GigE vision. Intel PRO/1000 GT PCI network interface controller. In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the term applied to transmitting Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T, is defined by the IEEE 802.3ab standard.

  7. Charge-transfer insulators - Wikipedia

    en.wikipedia.org/wiki/Charge-transfer_insulators

    Charge-transfer insulators are a class of materials predicted to be conductors following conventional band theory, but which are in fact insulators due to a charge-transfer process. Unlike in Mott insulators, where the insulating properties arise from electrons hopping between unit cells, the electrons in charge-transfer insulators move between ...

  8. Ethernet physical layer - Wikipedia

    en.wikipedia.org/wiki/Ethernet_physical_layer

    The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices.

  9. Multi-mode optical fiber - Wikipedia

    en.wikipedia.org/wiki/Multi-mode_optical_fiber

    Multi-mode optical fiber. Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 800 Gbit/s. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits ...
