Thermal conductivity of CaF at high pressure
Somayeh Faraji, S. Mehdi Vaez Allaei, Maximilian Amsler
We study the thermal transport properties of three CaF polymorphs up to a pressure of 30 GPa using first-principle calculations and an interatomic potential based on machine…
Ultra-high lattice thermal conductivity and the effect of pressure in superhard hexagonal BC2N
Safoura Nayeb Sadeghi, S. Mehdi Vaez Allaei, Mona Zebarjadi +1
Hexagonal BCN is a superhard material recently identified to be comparable to or even harder than cubic boron nitride (c-BN) due the full bonding character and the hig…
Inter-layer and Intra-layer Heat Transfer in Bilayer/Monolayer Graphene van der Waals Heterostructure: Is There a Kapitza Resistance Analogous?
Ali Rajabpour, Zheyong Fan, S. Mehdi Vaez Allaei
Van der Waals heterostructures have exhibited interesting physical properties. In this paper, heat transfer in hybrid coplanar bilayer/monolayer (BL-ML) graphene, as a model layere…
Kapitza thermal resistance across individual grain boundaries in graphene
Khatereh Azizi, Petri Hirvonen, Zheyong Fan +4
We study heat transport across individual grain boundaries in suspended monolayer graphene using extensive classical molecular dynamics (MD) simulations. We construct bicrystalline…
Highly Anistoropic Thermal Conductivity of Arsenene: An ab initio Study
M. Zeraati, S. M. Vaez Allaei, I. Abdolhosseini Sarsari +2
Elemental 2D materials exhibit intriguing heat transport and phononic properties. Here we have investigated the lattice thermal conductivity of newly proposed arsenene, the 2D hone…
Crossing Statistics of Anisotropic Stochastic Surface
M. Ghasemi Nezhadhaghighi, S. M. S. Movahed, T. Yasseri +1
In this paper, we propose crossing statistics and its generalization, as a new framework to characterize the anisotropy in a 2D field, e.g. height on a surface, extendable to highe…
Universality and conformal non-invariance in self-affine rough surfaces
S. Hosseinabadi, M. A. Rajabpour, M. Sadegh Movahed +1
We show numerically that the roughness and growth exponents of a wide range of rough surfaces, such as random deposition with relaxation (RDR), ballistic deposition (BD) and restri…
Localization of elastic waves in heterogeneous media with off-diagonal disorder and long-range correlations
F. Shahbazi, Alireza Bahraminasab, S. Mehdi Vaez Allaei +2
Using the Martin-Siggia-Rose method, we study propagation of acoustic waves in strongly heterogeneous media which are characterized by a broad distribution of the elastic constants…
Stochastic Analysis and Regeneration of Rough Surfaces
G. R. Jafari, S. M. Fazeli, F. Ghasemi +4
We investigate Markov property of rough surfaces. Using stochastic analysis we characterize the complexity of the surface roughness by means of a Fokker-Planck or Langevin equation…
