Electron backscattering in a cavity: Ballistic and coherent effects
Electron backscattering in a cavity: Ballistic and coherent effects
Numerous experimental and theoretical studies have focused on low-dimensional systems locally perturbed by the biased tip of a scanning force microscope. In all cases either open or closed weakly gate-tunable nanostructures have been investigated, such as quantum point contacts, open or closed quantum dots, etc. We study the behavior of …
