TL;DR: This work implements a new physical mechanism for suppressing radiative losses of individual nanoscale resonators to engineer special modes with high quality factors: optical bound states in the continuum (BICs), and demonstrates that an individual subwavelength dielectric resonator hosting a BIC mode can boost nonlinear effects increasing second-harmonic generation efficiency.
Abstract: Subwavelength optical resonators made of high-index dielectric materials provide efficient ways to manipulate light at the nanoscale through mode interferences and enhancement of both electric and magnetic fields. Such Mie-resonant dielectric structures have low absorption, and their functionalities are limited predominantly by radiative losses. We implement a new physical mechanism for suppressing radiative losses of individual nanoscale resonators to engineer special modes with high quality factors: optical bound states in the continuum (BICs). We demonstrate that an individual subwavelength dielectric resonator hosting a BIC mode can boost nonlinear effects increasing second-harmonic generation efficiency. Our work suggests a route to use subwavelength high-index dielectric resonators for a strong enhancement of light-matter interactions with applications to nonlinear optics, nanoscale lasers, quantum photonics, and sensors.

13 May 1996TL;DR: In this article, a new method for minority carrier lifetime determination using a contactless photoconductance instrument in a quasi-steady-state mode was proposed, which permits the use of simpler electronics and light sources, yet has the capability to measure lifetimes in the nanosecond to millisecond range.
Abstract: This paper describes a new method for minority-carrier lifetime determination using a contactless photoconductance instrument in a quasi-steady-state mode. Compared to the more common transient photoconductance decay approach, the new technique permits the use of simpler electronics and light sources, yet has the capability to measure lifetimes in the nanosecond to millisecond range. In addition, by analyzing the quasi-steady-state photoconductance as a function of incident light intensity, an implicit I/sub SC/-V/sub OV/ curve can be obtained for noncontacted silicon wafers and solar cell precursors.

TL;DR: Data from a general population sample suggest this instrument to be sufficiently valid and reliable, and also sensitive to predictable variations between sociodemographic groups, to justify its use in clinical and epidemiological studies, both in psychiatry and general medicine.
Abstract: It is generally recognized that social relationships occupy a central position in psychiatry. To examine the role of social relationships in the onset of minor psychiatric morbidity it is necessary to construct an instrument which will meet the need for a valid, reliable and comprehensive index of social relationships. Such an instrument has now been developed and used in a sample of the general population. The Interview Schedule for Social Interaction arose from a research need, and was constructed to assess the availability and perceived adequacy for any individual of a number of facets of social relationships. These consist both of persons and of the provisions obtained through them. Data from a general population sample suggest this instrument to be sufficiently valid and reliable, and also sensitive to predictable variations between sociodemographic groups, to justify its use in clinical and epidemiological studies, both in psychiatry and general medicine.

TL;DR: In this paper, the authors show that specific ion adsorption due to dispersion interactions can be dominant even at charged interfaces especially at high salt concentrations (∼0.1 ε).
Abstract: Present theories of colloid science do not account for specific ion effects as exemplified by the Hofmeister effect, surface tension of electrolyte solution interfaces, binding to micelles, effective charge in double layer interactions, and attractive interactions in low Hamaker constant systems. It is argued that specificity emerges naturally and can be rationalized if dispersion interactions acting on ions are included in the theory. These are in principle accessible from bulk solution properties. Specific ion adsorption due to dispersion interactions can be dominant even at charged interfaces especially at high salt concentrations (∼0.1Μ). The effects can be qualitatively different at air−water and oil−water surfaces. That part of extended Lifshitz theory for low Hamaker constant systems, in which the forces are mainly due to temperature and salt dependent interaction, is re-examined. It is shown to be at the same level of approximation as, and precisely equivalent to, the Onsager limiting law for the ...
