TL;DR: It is demonstrated that ultraviolet Raman spectroscopy is an effective technique to measure the transition temperature (Tc) in ferro electric ultrathin films and superlattices and reveals the essential roles of electrical and mechanical boundary conditions for nanoscale ferroelectricity.
Journal ArticleDOI
Confinement of acoustical vibrations in a semiconductor planar phonon cavity.
TL;DR: It is shown that acoustical phonons can be confined in such layered structures when the spacer thickness is an integer multiple of the acoustic half-wavelength at the center of one of the superlattice folded minigaps.
Journal ArticleDOI
Resonance effects in the Raman scattering of monolayer and few-layer MoSe 2
TL;DR: Soubelet et al. as mentioned in this paper, Pedro Ignacio et al., 2013. Consejo Nacional de Investigaciones Cientificas y Tecnicas; Argentina.
Journal ArticleDOI
Critical coupling to Tamm plasmons
TL;DR: In this article, the conditions of critical coupling of light to Tamm plasmons are investigated with comprehensive numerical simulations, highlighting the parameters that maximize absorption of incident light in the metal layer.
Journal ArticleDOI
Micropillar Resonators for Optomechanics in the Extremely High 19-95-GHz Frequency Range.
