TL;DR: This work presents a new spectrometer with an ultrahigh resolution of better than 0.012 nm/pixel in the 170–600nm spectral region using a grating-integrated module that consists of 19 subgratings without any moving parts.
Journal ArticleDOI
Strong quantum size effects in transition metal silicide ultrathin films: Critical role of Fermi surface nesting
TL;DR: In this article, the authors used first-principles calculations based on density functional theory to study the quantum size effects (QSEs) of CoSi2 ultrathin films with different thickness.

TL;DR: In this paper, a series of NixSiO2(1−x) granular films were prepared by ion sputtering, and some of them were annealed, and the complex dielectric function and magneto-optical polar Kerr spectra of the samples were measured in the 1.5 −4.5 eV photon energy range at room temperature.
Proceedings ArticleDOI
Magneto-optical and optical properties of GdFe films
TL;DR: In this paper, the magneto-optical Kerr effect in the large energy range between 1.6 eV and 4.5 eV was studied using spectroscopic ellipsometry.
