In this work, we presented our preliminary ab initio results for the vibrational modes and the phonon frequencies of the SiC (100) surfaces. Our results are in good agreement with the available experimental data whenever this comparison is possible. For the accepted models of the C-terminated surfaces in the c(2×2) reconstruction, while in the bridge-dimer model there is an acetylene-like vibra...
In this work, we have calculated ab initio the vibrational modes and the phonon frequencies for the SiC (100) surfaces. Our results are in good agreement with the available experimental data whenever this comparison is possible: in fact, most of our obtained results are predictions. For the accepted models of the C-terminated surfaces in the c(2!2) reconstruction, while in the bridge-dimer mode...
Energy decay plays a central role in a wide range of phenomena, such as optical emission, nuclear fission, and dissipation in quantum systems. Energy decay is usually described as a system leaking energy irreversibly into an environmental bath. Here, we report on energy decay measurements in nanomechanical systems based on multilayer graphene that cannot be explained by the paradigm of a system...
