Biomechanical properties of mammalian bones, such as strength, toughness, and plasticity, are
essential for understanding how microscopic-scale mechanical features can link to macroscale bones’ strength
and fracture ...

(Journal of Applied Physics, 2016-04)
We have fabricated Si-on-insulator (SOI) layers with a thickness h1 of a few nanometers and
examined them by Raman spectroscopy with 363.8 nm excitation. We have found that phonon and
electron confinement play important ...
