  • Abstract
    Experimental and theoretical evidence of the formation of `transverse´ Gunn dipoles in an Al0.23Ga0.77As/In 0.23Ga0.77As delta doped HEMT is presented. Monte Carlo simulations predicted that the dipoles would first cause a sudden reduction in current followed by a gradual upturn. These predictions were in excellent agreement with the experimental observations
