چکیده
: We study numerically the phonon dispersion relations and corresponding displacement fields for a circular cross-section nanowire superlattices consisting of anisotropic GaN and AlN. We determine a set of parameters which gives complete phononic bandgaps. The results suggest the potential for manipulating phonons in the micro/nano electromechanical systems.

Acoustic phonon modes and dispersion relations of nanowire superlattices.
We study theoretically acoustic phonon modes in nanowire superlattices (NWSLs) composed of cubic materials. We classify the acoustic phonon modes in rectangular and square cross-section NWSLs, based on group theory. For NWSLs consisting of GaAs and AlAs, we calculate numerically the dispersion relations of each phonon mode and corresponding displacement fields. We examine the effects of both th...

Infrared reflection spectra of bulk semiconductors and superlattices can be predicted mathematically with optical phonon frequencies as some of the input variables. This method will be used to determine the polar longitudinal and transverse optical phonons modes and their corresponding energies that are present in AlN/GaN superlattices. Theoretical results will be compared to reflection experim...
متن کاملHeat-Transport Mechanisms in Superlattices
Superlattices are important structures for thermoelectric applications because of their potential for achieving high efficiency for thermoelectric energy conversion. Despite numerous theoretical and experimental studies, basic understanding of the thermal conductivity L of superlattices is incomplete. In semiconductors, heat is carried by wave-like lattice vibrations, i.e., phonons, with a broa...

GaN and AlN compounds have been proven useful in wide bandgap microelectronics and optoelectronics. Also properties of bulk GaN and AlN have been studied extensively. However, many characteristics of AlGaN/GaN superlattices are not well known. In particular, the properties of phonons have not been determined. In order to determine phonon properties, this study measured infrared reflectivity spe...
