In contrast, room-temperature tetragonal distortion decreased as the film became thinner. This study reveals the effect of in-plane tensile strain in (100)/(001)-oriented epitaxial PbTiO3films with higher Tc and smaller tetragonal distortion at room temperature. 展开 ...
Nanotwinned Cu exhibits an unusual combination of ultra-high strength and high tensile ductility. However, its fracture behavior and associated microscopic mechanisms remain largely unexplored. Here we study the fracture in a free-standing thin film of nanotwinned Cu using molecular dynamics (MD) simula...
We have developed a new methodology to study the effect of mechanical stress on spin waves in thin films deposited onto compliant substrates. It is based on micro-tensile tests combined with Brillouin light-scattering spectroscopy, which allows in situ probing of the magnetization dynamics of the ...
Another form of naturally occurring wellbore failure is drilling-induced tensile fractures. These fractures form in the wall of the borehole at the azimuth of the maximum horizontal compressive stress when the circumferential stress acting around the well locally goes into tension; they are not seen...
On the out-of-plane deformation of freestanding micro-rings for tensile stress measurements Micro-Rings have been widely used for measurement of residual tensile stress in thin films. This measurement approach provides a simple and convenient way ... YC Chen,MA Maher,HD Stewart,... - Micromachin...
Mo films were deposited via magnetron sputtering with two different deposition geometries: dynamic deposition (moving substrate) and static deposition (fixed substrate). The residual stress and structural morphologies of these films were investigated, with particular focus on in-plane anisotropy of the bi...
Micro Raman analysis shows the presence of slight tensile stress in the freestanding GaN crystals and no stress accumulation in HVPE GaN layers during the growth. Additionally, it is demonstrated that the residual tensile stress in HVPE GaN is caused only by elastic stress arising from the crystal...
