Optical Properties of Bismuth Nanostructures Towards the Ultrathin Film Regime
, 2019 Bulk bismuth presents outstanding optical properties, such as a giant infrared refractive index (n near 10) and a negative ultraviolet visible permittivity induced by giant interband electronic transitions. Although such properties are very appealing for

In-situ growth studies of sputtered ybco thin films by spectroscopic ellipsometry [PDF]
, 1997 Using spectroscopic ellipsometry we studied in-situ the growth of off-axis sputtered YBa2Cu3O6+x thin films on (001) SrTiO3 as a function of the deposition parameters. Especially in the very first growth stage (106A cm¿2 @ 77 K) is smooth and homogeneous,

New type of ellipsometry in infrared spectroscopy: The double-reference method
, 2008 We have developed a conceptually new type of ellipsometry which allows the determination of the complex refractive index by simultaneously measuring the unpolarized normal-incidence reflectivity relative to the vacuum and to another reference media. From

Transient dielectric function dynamics driven by coherent phonons in Bismuth crystal
Journal of the European Optical Society-Rapid PublicationsIn this study, we investigate the ultrafast transient dynamics of the dielectric function in bismuth crystal, excited by femtosecond laser pulses and modulated by coherent phonons. The primary aim is to understand the influence of the coherent A1g phonon

Organic LEDs Based on Bis(8-hydroxyquinoline) Zinc Derivatives with a Styryl Group
Molecules, 2023 For the first time, organic light-emitting diodes (OLEDs) based on bis(8-hydroxyquinoline) zinc with a styryl group (ZnStq) dispersed in poly(N-vinylcarbazole) matrix (ZnStq_R:PVK, where R = H, Cl, OCH3) were fabricated.

Intrinsic Stokes parameters for 3D and 2D polarization states [PDF]
Journal of the European Optical Society-Rapid Publications, 2015 The second-order characterization of a three-dimensional (3D) state of polarization is provided either by the corresponding 3D coherency matrix or (equivalently) by the associated 3D Stokes parameters. The analysis of the polarization properties that are

The wave impedance of an atomically thin crystal
, 2015 I propose an expression for the electromagnetic wave impedance of a two-dimensional atomic crystal, and I deduce the Fresnel coefficients in terms of this quantity.
