(Institut Català de Nanociència i Nanotecnologia)
Controlling thermal energy transfer at the nanoscale and thermal properties has become critically important in many applications since it often limits device performance. In this study, the effects on thermal conductivity arising from the nanoscale structure of free-standing nanocrystalline silicon films and the increasing surface-to-volume ratio when fabricated into suspended optomechanical nanobeams are studied.

Departament d'Enginyeria Electrònica) ; Aymerich Humet, Xavier (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
Several breakdown events and multilevel current fluctuations have been observed when ultrathin SiO2 films are subjected to constant-voltage stresses. These breakdown events are sometimes reversible, and consist in a local change of conduction mechanism. [...]

4 p, 252.9 KB Memory and nonlocal effects in heat transport : from diffusive to ballistic regimes / Àlvarez Calafell, Francesc Xavier (Universitat Autònoma de Barcelona. Departament de Física) ; Jou i Mirabent, David, 1953- (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
The authors discuss a generalized transportmodel including memory and nonlocal effects, which aims to describe the transition of heat transport from the diffusive regime to the ballistic regime. By using an effective thermal conductivity depending on the Knudsen number, they describe in a single equation the behavior of conductivity in terms of the system size and a reduction in the limit flux through nanoscale devices.
