Unveiling a crystalline topological insulator in a Weyl semimetal with time-reversal symmetry
(American Physical Society, 2014-09)
We consider a natural generalization of the lattice model for a periodic array of two layers, A and B , of spinless electrons proposed by Fu [Phys. Rev. Lett. 106, 106802 (2011)] as a prototype for a crystalline insulator. ...
Topological Crystalline Insulator in a New Bi Semiconducting Phase
(2016)
Topological crystalline insulators are a type of topological insulators whose topological surface states are protected by a crystal symmetry, thus the surface gap can be tuned by applying strain or an electric field. In ...

Effects of thermal annealing on the semi-insulating properties of radio frequency magnetron sputtering-produced germanate thin films
(Elsevier B.V. Sa, 2012-01-31)
We report the effects of thermal annealing on the semi-insulating properties of germanate thin films produced by a radio frequency magnetron sputtering process. Electrical and physical characterizations are presented. In ...

Multi-length and time scale thermal transport using the lattice Boltzmann method with application to electronics cooling
(PERGAMON-ELSEVIER SCIENCE LTD, 2006)
The lattice Boltzmann method (LBM) is used to investigate one-dimensional, multi-length and -time scale transient heat conduction in crystalline semiconductor solids, in which sub-continuum effects are important. The ...
Theoretical and experimental study of topological invariants in topological crystalline insulators
(UniandesMaestría en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2019)
The topological crystalline Insulators (TCI) are topological materials with metallic surface states protected by a symmetry given by the crystalline structure, and not by the Time reversal one as in the usual topological ...
Understanding topological insulators in real space
(MDPI, 2021)
A real space understanding of the Su-Schrieffer-Heeger model of polyacetylene is introduced thanks to delocalization indices defined within the quantum theory of atoms in molecules. This approach enables to go beyond the ...
