Definition of charge carrier in English:

charge carrier


  • 1A particle which carries an electric charge.

    • ‘Now think of a charge carrier - an electron, say - in the n-type region.’
    • ‘The n- and p- stand for Negative and Positive, as the dominant charge carrier in n-type materials are the negative electrons.’
    • ‘In a conductor, say a metal wire, the charge carriers are able to move under the influence of even a tiny electric field.’
    • ‘A laser beam, by itself, cannot conduct electricity because it contains no charge carriers such as electrons to produce a current flow.’
    • ‘More current means more charge carriers are filling the plates of the capacitor and eventually once enough of them line up on the plates, they increase the voltage across a capacitor.’
    1. 1.1A mobile electron or hole by which electric charge passes through a semiconductor.
      • ‘At these low temperatures the mobility edge can be probed without the complication of thermal activation - a process that assists charge carrier transport in semiconductors due to large thermal energy at high temperatures.’
      • ‘We can now take a moment to discuss some of the properties of the two types of charge carriers; electrons and holes.’
      • ‘This is due to the difficulty of maintaining control of charge carriers moving through the transistor when using only a single gate.’
      • ‘Electrons are not the only charge carriers; holes, or open spaces in bonding sites can also be used in conduction.’
      • ‘However, by providing a means for electrons to move, it effectively serves as a conductive charge carrier.’
