Quasi-ballistic transport in HgTe quantum-well nanostructures
arXiv:cond-mat/0305078 · doi:10.1063/1.1602170
Abstract
The transport properties of micrometer scale structures fabricated from high-mobility HgTe quantum-wells have been investigated. A special photoresist and Ti masks were used, which allow for the fabrication of devices with characteristic dimensions down to 0.45 $μ$m. Evidence that the transport properties are dominated by ballistic effects in these structures is presented. Monte Carlo simulations of semi-classical electron trajectories show good agreement with the experiment.
