3.10 Non-linear effects

Abstract

This chapter discusses non-linear effects of a ballistic quantum point contact (QPC). The suppression of collision noise in an electron beam splitter is illustrated as a function of output current. The measured auto-correlation of the transmitted current and cross-correlation between transmitted and reflected currents are shown as a function of the total current through the QPC device. The current-voltage characteristics of the ballistic QPC are illustrated. The evolution of additional quantized conductance plateaux with increasing bias is illustrated. The differential conductance is plotted as a function of the applied source-drain bias for different gate voltages.
