Intermediate band solar cells (IBSCs) are designed to enhance the photovoltaic efficiency significantly over that of a single-junction solar cell as determined by the Shockley–Queisser limit. In this work we present calculations to determine parameters of type-II Zn1−xCdxTe/Zn1−yCdySe quantum dots (QDs) grown on the InP substrate suitable for IBSCs. The calculations are done via the self-consistent...
In this paper we revisit the issue of mechanical action of light confined within optical cavities. While the traditional view holds that the modification of the resonant frequencies of the cavities via mechanical motion is the main source of optomechanical interaction, we demonstrate that in the case of cavities with degenerate modes, confinement of light modifies the optical forces in more dramatic...
A model of the optomechanical interaction of a nanoparticle and a spherical Whispering Gallery Mode microresonator is derived. The theory furnishes exact equations of motion and describes the observed circular orbits of the particle.
Multi-sphere Mie theory is used to analyze the resonance response and the spatial distribution of the electromagnetic field in a system of a linear chain of microspheres. We assume that the system is coupled to a monochromatic source that would have excited a fundamental whispering gallery mode in a single sphere, and study the modification of the resonance frequencies and the spatial distribution...
