• Theory of the Linewidth of Intersubband Plasmons in Quantum Wells 

    Ullrich, Carsten A.; Vignale, Giovanni, 1957- (American Physical Society, 2001)
    Intersubband (ISB) plasmons in remotely doped wide quantum wells acquire a linewidth even at zero temperature and in-plane wave vector q∥ = 0 by a combination of intrinsic (electron-electron interaction) and extrinsic ...
