چکیده

In this work, by using the density-functional theory within the local density approximation, plane wave expansions and the pseudopotential method, we present our preliminary results for the strain-induced shifts of the zone center phonon modes and of the effective charges on the III-Nitrides. Our results are in good agreement with the experiment as well as with other calculations, whenever a comparison is possible.

Pressure-stiffened Raman phonons in group III nitrides: a local bond average approach.

It has long been puzzling regarding the atomistic origin of the pressure-induced Raman optical phonon stiffening that generally follows a polynomial expression with coefficients needing physical indication. Here, we show that an extension of the bond-order-length-strength correlation mechanism and a local bond average approach to the pressure domain have led to an analytical solution to connect...

Observation of the First-Order Raman Scattering in SrTiO3 Thin Films

We have studied lattice dynamic properties of SrTiO3 thin films from 5 to 300 K using metaloxide bilayer Raman scattering. First-order zone-center optical phonons, symmetry forbidden in single crystals, have been observed in the thin films, indicating strain-induced lowering of symmetry. The asymmetric line shape of the TO2 phonon is interpreted as evidence for micropolar regions in the thin fi...

Planar Force-Constant Method for Lattice Dynamics of Cubic III-Nitrides

Using the density-functional theory within the Full Potential Linear Augmented PlaneWave (FP-LAPW) method, we have calculated, in this work, the equation of state, the e ective charges and the phonon dispersion along [100] and [111] directions for the cubic III-Nitrides(c-BN, c-AlN, c-GaN and c-InN), including hydrostatic strains dependence. A good agreement with the micro-Raman scattering expe...

Biaxial strain in graphene adhered to shallow depressions.

Measurements on graphene exfoliated over a substrate prepatterned with shallow depressions demonstrate that graphene does not remain free-standing but instead adheres to the substrate despite the induced biaxial strain. The strain is homogeneous over the depression bottom as determined by Raman measurements. We find higher Raman shifts and Gruneisen parameters of the phonons underlying the G an...

The Effect of Celecoxib, a Cyclooxygenase-2 Inhibitor on Noise- Induced Hearing Loss

Objective(s): Noise-induced hearing loss (NIHL) is the major cause of acquired hearing loss.  Celecoxib, a cyclooxygenase-2 (COX-2) inhibitor, is a non- steroidal anti- inflammatory drug (NSAID) with known antioxidant and antineoplastic activity. Therefore, we monitored the extent of temporary noise- induced threshold shifts (TTS) and cochlear damage caused by high level 4- kHz noise exposure t...
