| dc.description | A sharp step-like structure, which is seen in the current-voltage characteristic of a laterally confined AlGaAs/GaAs resonant tunnelling structure, is a novel manifestation of a quantum effect arising when one-dimensional wires feed electrons into a zero-dimensional quantum box. The authors can analyse the data to deduce a tunnelling time, an inelastic scattering time and the transmission probability for electrons in this system. The height of the current steps, Delta I, gives the electron tunnelling time, tau<sub>e</sub>, via Delta I=e/2 tau<sub>e</sub>, while the differential conductance gives the peak transmission probability, T<sub>0</sub>, via G approximately (e<sup>2</sup>/h)T<sub>0</sub>. The authors must invoke inelastic scattering to explain the low value of T<sub>0</sub> approximately 9% obtained from the data, and so they find that tunnelling in their structure is sequential. |
