  • Solitary-wave conduction in p-type Ge under time dependent voltage bias 

    Bergmann, Michael J.; Teistworth, Stephen W.; Bonilla, Luis L.; Rodríguez Cantalapiedra, Inma (American Physical Society, 1996-01-01)
    Article
    Restricted access - publisher's policy
    We present the results of numerical simulations of a drift-diffusion model—including electric-field-dependent generation-recombination processes—for closely compensated p-type Ge at low temperature and under dc+ac and ...
  • Solitary-wave dynamics in extrinsic semiconductors under dc voltage bias 

    Rodríguez Cantalapiedra, Inma; Bonilla, Luis L.; Bergmann, Michael J.; Teitsworth, Stephen W. (American Physical Society, 1993-10-01)
    Article
    Restricted access - publisher's policy
    Numerical-simulation results are presented for a simple drift-diffusion model which describes timedependent and nonlinear electrical transport properties of extrinsic semiconductors under timeindependent (dc) voltage ...
  • Universality of the Gunn effect: self-sustained oscillations mediated by solitary waves 

    Bonilla, Luis L.; Rodríguez Cantalapiedra, Inma (American Physical Society, 1997-09-30)
    Article
    Open Access
    The Gunn effect consists of time-periodic oscillations of the current flowing through an external purely resistive circuit mediated by solitary wave dynamics of the electric field on an attached appropriate semiconductor. By ...
