Refractive index of different perovskite materials

Journal of Materials Research, 2021
The perovskite solar cell technologies are the hope of satisfying the huge demand of tomorrow’s energy requirements. The inorganic, organic and mixed perovskite materials are the backbone of modern solar cells. The energy band gap and refractive index of

Index of refraction of germanium

Applied Optics, 2020
Measurements of the index of refraction of a sample of high-quality, single-crystal germanium using the minimum deviation refractometry method are presented for temperatures near 22°C and for wavelengths in the range 2 to 14 µm. The standard uncertainty for the measurements ranges from 1.5 × 10 −

Optical Refractive Index Sensors with Plasmonic and Photonic Structures: Promising and Inconvenient Truth

Advanced Optical Materials, 2019
Optical sensors are widely used for refractive index measurement in chemical, biomedical, and food processing industries. Due to specific field distribution of the resonances, optical sensors provide high sensitivity to ambient refractive index ...

Microchannel-based plasmonic refractive index sensor for low refractive index detection.

Applied Optics, 2019
A microchannel incorporated photonic crystal fiber (PCF)-based surface plasmon resonance (SPR) sensor for detection of low refractive index (RI) at near-infrared wavelength is presented in this paper. To attain a simple and practically feasible mechanism,

Exposure-dependent refractive index of Nanoscribe IP-Dip photoresist layers.

Optics Letters, 2019
The refractive indices of photoresists used for direct laser writing (DLW) have been determined after exposure to ultraviolet (UV) light. However, it was anticipated that the refractive index will differ when applying a two-photon polymerization (TPP ...

Realization of ultrahigh refractive index in terahertz region by multiple layers coupled metal ring metamaterials

Journal Electromagnetic Waves and Applications, 2019
We report a polarization-independent unnaturally high refractive index metamaterial. It is found that the effective permittivity of the designed metamaterial can be drastically increased by the capacitive coupling effect. Also, the effective permeability

Refractive index of GaN

Physica Status Solidi (a), 1971
The refractive index of GaN and its temperature dependence have been measured using plane-parallel platelets with E ⊥ c. In this direction at 300 K the index is 2.67 at 3.38 eV, 2.33 at 1.0 eV, and has an extrapolated value of 2.29 ± 0.005 at 0 eV. The difference in the refractive indices for E ⊥ c and E ‖ c is 1.5 ± 0.2% at 5000 A. A Debye temperature
