Band gaps of acoustic waves propagating in a solid/liquid phononic fibonacci structure
(Elsevier, 2010-09-01)
Strong Optical-Mechanical Coupling in a Vertical GaAs/AlAs Microcavity for Subterahertz Phonons and Near-Infrared Light
(American Physical Society, 2013-01)
We show that distributed Bragg reflector GaAs/AlAs vertical cavities designed to confine photons are automatically optimal to confine phonons of the same wavelength, strongly enhancing their interaction. We study the ...
Light Absorption near Threshold with Phonon Participation for Impurities in Semiconductors
(Sociedade Brasileira de Física, 2002)
It is presented a simple model for the calculation of the transition rate for impurities in semiconductors in which electron-phonon interaction is taken into account in a second order time dependent perturbation theory. ...
Tunable ultrasonic phononic crystal controlled by infrared radiation
(APPLIED PHYSICS LETTERS, 2018)
PHONON-SPECTRA OF RANDOMLY DISORDERED SYSTEM
(Elsevier B.V., 1991-02-01)
We study the phonon density of states of a three dimensional disordered mixed crystal NaCl(x)Br1-x. The phonon structure is obtained by using a cluster method based on a continued fraction expansion of the Green function. ...
Phonon optical modes and electronic properties in diamond nanowires
(Elsevier B.V., 2011)
PHONON SIDE BANDS IN THE OPTICAL-EMISSION OF ZINCBLENDE-TYPE SEMICONDUCTORS
(American Physical SocCollege PkEUA, 1993)
Using inelastic scattering of light to understand the nature of electron-phonon interactions and phonon self-energy renormalizations in graphene materials
(Universidade Federal de Minas GeraisUFMG, 2012-09-13)
In the last decade, many theoretical and experimental achievements have been made in the physics of graphene. In particular, Raman spectroscopy has been playing an important role in unraveling the properties of graphene ...
Slow light and slow acoustic phonons in optophononic resonators
(American Physical Society, 2016-11-15)
Slow and confined light have been exploited in optoelectronics to enhance light-matter interactions. Here we describe the GaAs/AlAs semiconductor microcavity as a device that, depending on the excitation conditions, either ...
