Conductividad térmica en metales, semiconductores, dieléctricos y materiales amorfos/ Thermal conductivity in metals, semiconductors, dielectrics and amorphous materials

Resumen en español Se estudia la física de la conductividad térmica y sus aspectos más importantes en una variedad de materiales. La conductividad térmica es influenciada por diferentes mecanismos de dispersión de fonones o electrones, los cuales limitan el transporte de energía térmica en el sólido. La conductividad térmica a una temperatura cercana al 80% de la temperatura de fundición es elevada en metales (~300 W/mK) y en semiconductores (~22 W/mK); es baja en dieléctricos (~ (mas) 6 W/mK) y es muy baja en materiales amorfos (~1,5 W/mK). En particular, en materiales amorfos la muy baja conductividad térmica es consecuencia del desorden atómico y de la ocurrencia de procesos de dispersión asociados a la existencia de potenciales de pozo doble asimétricos y a la presencia de modos vibracionales localizados. El propósito de este estudio es revisar las teorías existentes para explicar la conductividad térmica en sólidos y así identificar aspectos o procesos físicos relevantes en el régimen de muy altas temperaturas y antes de la temperatura de fundición, que nos permita articular las conclusiones en un referencial que nos sirva de guía para la especificación y preparación de materiales que puedan ser usados en la elaboración de la nueva generación de barreras térmicas. Nuestro interés se restringe al estudio de la conductividad térmica en sólidos dieléctricos a muy altas temperaturas, en donde hemos encontrado que la contribución de los fonones con un camino libre medio del orden de las dimensiones de las constantes de la red es muy importante y en algunos casos también se logra identificar una contribución relevante por parte de los electrones y/o fonones localizados (fractones localizados). Resumen en inglés We studied the physics underlying thermal conductivity and the most important thermal properties in a myriad of materials. Thermal conductivity is determined by different phonons or electron scattering mechanisms that limit the transport of thermal energy inside the solid. For the sake of the analysis, thermal conductivity close to 80% of melting point in metals is elevated (~300 W/mK) and low in semiconductors (~22 W/mK); is lower in dielectrics (~6 W/mK) and is very low (mas) in amorphous materials (~1,5 W/mK). The very low thermal conductivity in amorphous materials is a consequence of the atomic disorder, the occurrence of scattering processes associated with the existence of asymmetric double-well potential and localized vibrational modes. The purpose of this study is to review existing theories explaining the thermal conductivity of solids and so identify issues or relevant physical processes with regard to conditions of very high temperature and near to the melting point that could be important when studying thermal conductivity. This would allow us to place the findings in a framework that could guide the functionalization and preparation of materials that can be used in the elaboration of the new generation of thermal barrier coatings. Our interest is restricted to the study of thermal conductivity at very high temperatures in dielectric solids, where we found that the contribution of phonons with a free path of the order of an interatomic spacing is very important and in some cases we also found relevant the contribution of electrons and/or localized phonons (fractons).

Brane Effects on Extra Dimensional Scenarios: A Tale of Two Gravitons

Lykken, J.; Carena, M.; Delgado, Antonio; Pokorski, S.; Quirós, Mariano; Wagner, C. E. M.

We analyze the propagation of a scalar field in multidimensional theories which include kinetic corrections in the brane, as a prototype for gravitational interactions in a four dimensional brane located in a (nearly) flat extra dimensional bulk. We regularize the theory by introducing an infrared c...

16 pages, 4 figures. | Since 1999 it became obvious that the would be `isomorphism' between the affine $\hat sl(2)$ algebra and the N=2 superconformal algebras, proposed by some authors, simply does not work. However, this issue was never properly discussed in the literature and, as a result, some c...
