FRIEDEL OSCILLATIONS IN ONE-DIMENSION: MANY IMPURITIES AND BIAS VOLTAGE EFFECTS. Authors: L. TUGULAN. |
||||||
Abstract:
Using the linear response theory we studied the Friedel oscillations in a one-dimensional noninteracting electron gas in the presence of impurities. The impurities potential is assumed to have periodic delta-function and square-well form. The particular cases of a single impurity, two and three impurities are also analyzed. The oscillations are strongly affected by the distance between impurities. The effect of the bias voltage on the Friedel oscillations in a wire with one impurity, coupled to macroscopic electrodes, is also analyzed. Keywords: One-dimensional electron gas, Many impurities, Short-range interactions, Friedel oscillations, Single impurity, Two impurities, Three impurities, Bias voltage effects. |
