143 p, 3.5 MB Electronic properties of organic semiconductors and low-dimensional materials / Boskovic, Desanka, autor. ; Ordejón Rontomé, Pablo, supervisor acadèmic. ; Sodupe Roure, Mariona, supervisor acadèmic. ; Universitat Autònoma de Barcelona. Departament de Química.
Los semiconductores orgánicos se han convertido en un grupo muy interesante de materiales por sus buenas propiedades de transporte de carga y aplicaciones tecnológicas masivas. Entre todos ellos, el rubreno ganó gran interés porque es un semiconductor orgánico con la movilidad más alta del portador, que puede alcanzar 40cm2=V s para los agujeros. [...]
Organic semiconductors became very interesting group of materials because of their good charge-transport properties and massive technological applications. Among all of them, rubrene gained grate interest because it is an organic semiconductor with the highest carrier mobility, which can reach 40cm2=V s for holes. [...]

203 p, 3.7 MB Gravity, holography and applications to condensed matter / Baggioli, Matteo ; Pujolás Boix, Oriol, dir. ; Universitat Autònoma de Barcelona. Departament de Física
Los sistemas fisicos fuertemente acoplados, junto a sus correspondientes y por lo general exoticas caracteristicas, son imposibles de tratar mediante los enfoques perturbativos convencionales que en estos casos no son capaces de proporcionar una herramienta controlable y robusta. [...]
Strongly coupled physical systems along with their corresponding, and usually exotic, features are elusive and not suitable to be described by conventional and perturbative approaches, which in those cases are not able to provide a controllable and robust tool for computations. [...]
