Abstract


  • The small signal response and thermal noise spectra in miniband superlattice are investigated. The

    properties of hot electron differential mobility, velocity fluctuation, and noise temperature are

    determined around a stationary condition. The field and frequency dependent drift velocity, electron

    energy, effective mass, and electron temperature are obtained. At low frequencies, noise temperature

    increases rapidly with the electric field. Our calculated noise temperatures for miniband superlattice

    are in good agreement with the experimental results, with the sample thickness estimated to be

    around 4 um.
