Journal ArticleDOI
Dynamic coupling of piezoelectric effects, spontaneous polarization, and strain in lattice-mismatched semiconductor quantum-well heterostructures
TL;DR: In this article, a static and dynamic analysis of the combined and selfconsistent influence of spontaneous polarization, piezoelectric effects, lattice mismatch, and strain effects is presented for a three-layer one-dimensional AlN∕GaN wurtzite quantum-well structure.
Journal ArticleDOI
Optical properties and optimization of electromagnetically induced transparency in strained InAs/GaAs quantum dot structures
Daniele Barettin,Jakob Houmark,Benny Lassen,Morten Willatzen,Torben Roland Nielsen,Jesper Mørk,Antti-Pekka Jauho +6 more
TL;DR: In this paper, the size and geometry dependence on the slow light properties of conical semiconductor quantum dots were studied using multiband k ·p theory and the V-type scheme for electromagnetically induced transparency EIT was identified and an optimal height and size for efficient EIT operation.
Journal ArticleDOI
Ultrasound transducer modeling-general theory and applications to ultrasound reciprocal systems
TL;DR: A tutorial presentation on the theory of reciprocal ultrasound systems is given, and a complete set of modeling equations for one-dimensional multi-layer ultrasound transducers is derived from first principles.
Journal ArticleDOI
Anomalous Topological Edge States in Non-Hermitian Piezophononic Media.
TL;DR: This work numerically employs the acoustoelectric effect in electrically biased and layered piezophononic media as a solid framework for non-Hermitian and nonreciprocal topological mechanics in the MHz regime and discusses how in-gap edge states in the same instant, counterintuitively are able to delocalize along the entire layered medium.
Journal ArticleDOI
Tunable acoustic double negativity metamaterial.
TL;DR: This work designs acousto-elastic surface modes that are similar to surface plasmons in metals and on highly conducting surfaces perforated by holes and combines a structure hosting these modes together with a gap material supporting negative modulus and collectively producing negative dispersion.
