In Situ Studies on the Influence of Surface Symmetry on the Growth of MoSe₂ Monolayer on Sapphire Using Reflectance Anisotropy Spectroscopy and Differential Reflectance Spectroscopy [PDF]

Nanomaterials
The surface symmetry of the substrate plays an important role in the epitaxial high-quality growth of 2D materials; however, in-depth and in situ studies on these materials during growth are still limited due to the lack of effective in situ monitoring ...

In Situ Optical Monitoring and Morphological Evolution of Si Nanowires Grown on Faceted Al₂O₃(0001) Substrates [PDF]

Nanomaterials
This paper presents the growth and in situ optical characterization of silicon nanowires (Si NWs) on Al2O3(0001) substrates that are thermally faceted using the atomic low angle shadowing technique (ATLAS) method. Annealing Al2O3 substrates in air before

Optical anisotropy of pristine and reduced V2O5(010) [PDF]

Scientific Reports
The optical anisotropy of pristine and reduced single crystalline (010) orientated $$\hbox {V}_{2}\hbox {O}_{5}$$ is presented. The reduction of $$\hbox {V}_{2}\hbox {O}_{5}$$ is complex due to the abundance of V-O phases, strong dependence on the ...

Circular Dichroism Reflectance Anisotropy of Chiral Atomically Thin Films [PDF]

Chemosensors
Recently, a technical modification of a Reflectance Anisotropy Spectroscopy (RAS) spectrometer has been proposed to investigate the circular dichroism (CD) of samples instead of the normally studied linear dichroism. CD-RAS measures the anisotropy of the

Reflectance anisotropy spectroscopy of magnetite (110) surfaces [PDF]

, 2014
Reflectance anisotropy spectroscopy (RAS) has been used to measure the optical anisotropies of bulk and thin-film Fe3O4(110) surfaces. The spectra indicate that small shifts in energy of the optical transitions, associated with anisotropic strain or ...

As/P exchange on InP(001) studied by reflectance anisotropy spectroscopy [PDF]

, 1997
Reflectance anisotropy spectroscopy (RAS) has been used to investigate the As/P exchange reaction for group V stabilized InP(001) surfaces exposed to As2 and/or P2, under molecular beam epitaxy conditions.

Near infrared reflectance spectroscopy compared with soil clay and organic matter content for estimating within-field variation in N uptake in cereals [PDF]

, 2008
Adjusting fertiliser applications to within-field variations in nitrogen (N) mineralisation during the growing season can increase yields, improve crop quality, reduce costs and decrease nutrient losses to the environment. Predicting such variations at a

Two Methods of Near Infrared Reflectance Spectroscopy for Determining the Digestibility and Energy Value of Feeds [PDF]

, 1997
Two groups of rations with known in vivo digestibility and energy values were used in this study. These rations were composed of Italian ryegrass only (lRO. n = 45), and combination of Italian ryegrass and concentrates (lRC, n = 58).

1 ML Wetting Layer upon Ga(As)Sb Quantum Dot (QD) Formation on GaAs Substrate Monitored with Reflectance Anisotropy Spectroscopy (RAS)

Advances in OptoElectronics, 2018
III/V semiconductor quantum dots (QD) are in the focus of optoelectronics research for about 25 years now. Most of the work has been done on InAs QD on GaAs substrate. But, e.g., Ga(As)Sb (antimonide) QD on GaAs substrate/buffer have also gained attention for the last 12 years.

A microprocessor-aided platform enabling surface differential reflectivity and reflectance anisotropy spectroscopy [PDF]

, 2021
Surface differential reflectivity (SDR) and reflectance anisotropy spectroscopy (RAS) [sometimes known as reflectance difference spectroscopy] are two well-known optical spectroscopies used in the investigation of surfaces and interfaces.
