TL;DR: In this article, a wavelet-based boundary wall method is used to compute both the electronic wave function and probability current in and around the resonator, and excellent agreement between the calculated and measured conductance resonances, and identify fine structure associated with the lemon billiard cavity modes.
Abstract: Coherent resonant tunneling peaks are observed in the conductance of a quantum point contact coupled to an open resonator in a two-dimensional electron gas as we tune the resonator's dimensions. A wavelet based boundary wall method is used to compute both the electronic wave function and probability current in and around the resonator. We find excellent agreement between the calculated and measured conductance resonances, and identify fine structure associated with the lemon billiard cavity modes.

TL;DR: In this paper, a number of novel quantum phenomena have been observed in fabricated structures of length scale ∾50-100 nm, and there is strong motivation to develop fabrication techniques which can routinely access sub-50 nm length scales in a variety of materials and measurement techniques that can spectroscopically probe the local electronic properties of “ultra” nanometer-scale devices.
Abstract: Recent advances in nanofabrication technology have provided access to continually smaller length scales. Consequently, a number of novel quantum phenomena—some of which have already been highlighted in this book— have been observed in fabricated structures of length scale ∾50–100 nm. Because of the clear possibility that additional novel effects will become manifest at even smaller dimensions, there is strong motivation to develop: (1) fabrication techniques which can routinely access sub-50 nm length scales in a variety of materials and (2) measurement techniques which can spectroscopically probe the local electronic properties of “ultra” nanometer-scale devices.
