Nanodisplacement measurements by frequency-modulated laser autodyne [PDF]

open access: yesИзвестия Саратовского университета. Новая серия Серия: Физика, 2021
Background and Objectives: Measurements of nanodisplacements are relevant for various applications of self-mixing laser (autodyne), in particular when they are combined with microwave probe methods, which are sensitive not only to the profile, but also ...

Dependence of Sheet Resistivity on Urbach Energy of Nano TiO2 - Graphene-based Electrode for DSSC Application [PDF]

open access: yes
The importance of renewable energy cannot be over-emphasized. Titanium IV oxide (TiO2 ) is the most suitable semiconductor for dye-sensitized solar cells (DSSC) due to its chemical stability, non-toxicity and excellent optoelectronic properties.

A hydrodynamical model for the Fermi-LAT γ-ray light curve of blazar PKS 1510-089

open access: yesEPJ Web of Conferences, 2013
A physical description of the formation and propagation of working surfaces inside the relativistic jet of the blazar PKS 1510-089 are used to model its γ -ray variability light curve using Fermi-LAT data from 2008 to 2012. The physical model is based on

Comparison of approximations to the transition rate in the DDHMS preequilibrium model

open access: yesEPJ Web of Conferences, 2014
The double differential hybrid Monte Carlo simulation model (DDHMS) originally used exciton model densities and transition densities with approximate angular distributions obtained using linear momentum conservation.

Three-body mechanisms in plasma recombination of H3+ and D3+ Ions

open access: yesEPJ Web of Conferences, 2015
The low-temperature plasma recombination of H3+ and D3+ ions with electrons partially occurs by three-body assisted (ternary) mechanisms that need to be better understood.

High Order Harmonic Generation in Three Pulse Scattering Geometry

open access: yesEPJ Web of Conferences, 2013
We study the generation of high order harmonics produced by the interaction of three intense and ultrafast noncollinear laser pulses. Harmonic radiation, not overlapped to the direction of the incident pulses, is observed.

Depth-dependent Detection Mechanisms of Coherent Phonons in n-type GaAs

open access: yesEPJ Web of Conferences, 2013
Transient reflectivity measurements at different probing wavelengths reveal detection mechanisms of coherent phonon and phonon-plasmon coupled modes of n-doped GaAs to be strongly depth-dependent due to the carrier depletion at the surface.

Searching a dark photon with HADES

open access: yesEPJ Web of Conferences, 2014
The existence of a photon-like massive particle, the γ‘ or dark photon, is postulated in several extensions of the Standard Model to explain some recent puzzling astrophysical observations, as well as to solve the sofar unexplained deviation between the ...

Cross-correlation video recording of gas-vapor-droplet two-phase flows

open access: yesEPJ Web of Conferences, 2015
The experimental investigations of gas-vapor-droplet two-phase flow formation during single water droplets and their aggregate motion through high-temperature (more than 1000 K) combustion products have been conducted with usage of cross-correlation ...

Reference Question Data Mining [PDF]

open access: yes, 2010
This exploratory study investigated the feasibility of using reference questions as an important tool in the construction of study guides, instructional outreach, and collection development at a small, four-year university in Lake Charles, Louisiana. The
