Brittle fracture studied by ultra-high speed synchrotron X-ray diffraction imaging
Antoine Petit, Sylvia Pokam, Frederic Mazen +7
Ever since the very first human-made knapped tools, the control of fracture propagation in brittle materials has been a vector of technological development. Nowadays, a broad range…
Interfacial closure of contacting surfaces
F. Rieutord, C. Rauer, H. Moriceau
Understanding the contact between solid surfaces is a long standing problem which has a strong impact on the physics of many processes such as adhesion, friction, lubrication and w…
Accurate strain measurements in highly strained Ge microbridges
A. Gassenq, S. Tardif, K. Guilloy +16
Ge under high strain is predicted to become a direct bandgap semiconductor. Very large deformations can be introduced using microbridge devices. However, at the microscale, strain…
Uniaxially stressed germanium with fundamental direct band gap
R. Geiger, T. Zabel, E. Marin +17
We demonstrate the crossover from indirect- to direct band gap in tensile-strained germanium by temperature-dependent photoluminescence. The samples are strained microbridges that…
