New deformation-induced nanostructure in silicon
(American Chemical Society, 2018-07)
Nanostructures in silicon (Si) induced by phase transformations have been investigated during the past 50 years. Performances of nanostructures are improved compared to that of bulk counterparts. Nevertheless, the confinement ...
Control mediante la presión y la temperatura de las propiedades ópticas en cristales fotónicos
(Universidad Nacional de ColombiaBogotá - Ciencias - Doctorado en Ciencias - FísicaFacultad de CienciasBogotáUniversidad Nacional de Colombia - Sede Bogotá, 2020-12)
Los cristales fotónicos son estructuras dieléctricas los cuales permiten el control de la propagación de la luz. En este trabajo presentamos los resultados teóricos referentes a las estructura de bandas fotónicas en cristales ...

Precision dicing of hard materials with abrasive blade
(Springer, 2016-10-01)
The present work shows the experiments on dicing of high alumina substrates using abrasive blades. The technology used by modern electronic components is based on narrow and thin ceramic and single crystal substrates. One ...
Nonhydrostatic compression of bismuth to 222 GPa: Some constraints on elasticity of the bcc-phase
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-10)
Polycrystalline bismuth sample was compressed in a diamond anvil cell and X-ray diffraction patterns from the body centered cubic phase of bismuth (bcc-Bi) recorded in the pressure range 12-222 GPa. The analysis of diffraction ...
