A near-field metalens is utilized to assist a conventional brightfield microscope for significantly enhancing the signal-to-noise ratio associated with a parallel bridge defect on a 7 nm node patterned wafer.
We compare the focusing of Gaussian and plane wave illumination for a cascaded asymmetric microstructure. Although the Gaussian beam generates a longer and wider photonic nanojet, it can still focus efficiently for non-optimal microstructure geometries.
A reflective microring resonator is used as a wavelength selective nonlinear feedback element in a fiber ring laser to generate optical clock pulses. All components are driven by DC current.
Optical microscopy is one of the most important scientific achievements in the history of mankind, and it is the most widely used technique for exploring the small world. However, as is well known, traditional lens-based optical microscopes suffer from the low imaging resolution λ/2 due to the diffraction limit. To overcome this obstacle, multiple innovative methods have been proposed during the past...
The dual-primal finite-element and interconnecting algorithm (FETI-DP) is efficiently applied in parallel to compute the far-field scattering from a wafer with sub-wavelength patterns. As a nonoverlapping domain decomposition method for solving large-scale problems, the FETI-DP algorithm formulates a global interface problem, whose iterative solution is accelerated by solving a global corner problem...
Recently, periodic nanostructures with a rectangular profile have been widely used in the backside layer of solar cells to reduce the reflectance and to enhance the performance. In this paper, we design solar cells by applying two-dimensional periodic nanostructures with a trapezoidal profile as an antireflective layer. Through intensive simulations using rigorous coupled-wave analysis (RCWA), we...
The paper analyzes the attributes and properties of the emerging hybrid network. The changes that the hybrid network has brought to information dissemination and the development of the social collective behaviors, as well as the challenges it has imposed on the management of the social clusters are discussed. Reviewing the previous researches based on network technologies, a new paradigm for hybrid...
Grain size effects on the dielectric properties of BaTiO3 (BTO) nanoceramics have been studied by using the modified Ginsburg-Landau-Devonshire (GLD) thermodynamic theory. Considering the existence of internal stresses, it is found that with decreasing grain size the transition temperature of cubic to tetragonal phase decreases. Temperature dependence of the dielectric constant of nano-grain BTO ceramic...
