Giant Tuning of Electronic and Thermoelectric Properties by Epitaxial Strain in p-Type Sr-Doped LaCrO3 Transparent Thin Films
D. Han, R. Moalla, I. Fina +8
The impact of epitaxial strain on the structural, electronic, and thermoelectric properties of p-type transparent Sr-doped LaCrO3 thin films has been investigated. For this purpose…
Role of a fractal shape of the inclusions on acoustic attenuation in a nanocomposite
Haoming Luo, Yue Ren, Anthony Gravouil +4
Nanophononic materials are promising to control the transport of sound in the GHz range and heat in the THz range. Here we are interested in the influence of a dendritic shape of i…
A continuum model reproducing the multiple frequency crossovers in acoustic attenuation in glasses
Haoming Luo, Valentina M. Giordano, Anthony Gravouil +1
Structured metamaterials are at the core of extensive research, promising for acoustic and thermal engineering. Nevertheless, the computational cost required for correctly simulati…
Elastic anomalies in glasses: the string theory understanding in the case of Glycerol and Silica
Ernesto Bianchi, Valentina M. Giordano, Fernando Lund
We present an implementation of the analytical string theory recently applied to the description of glasses. These are modeled as continuum media with embedded elastic string heter…
Enhanced thermal conductivity in percolating nanocomposites: a molecular dynamics investigation
Konstantinos Termentzidis, Valentina M. Giordano, Maria Katsikini +5
In this work we present a molecular dynamics investigation of thermal transport in a silica-gallium nitride nanocomposite. A surprising enhancement of the thermal conductivity for…
Propagative and diffusive regimes of acoustic damping in bulk amorphous material
Y. M. Beltukov, D. A. Parshin, V. Giordano +1
In amorphous solids, a non-negligible part of thermal conductivity results from phonon scattering on the structural disorder. The conversion of acoustic energy into thermal energy…
Nano-crystalline inclusions as a low-pass filter for thermal transport in a-Si
Tanguy Damart, Valentina Giordano, Anne Tanguy
We use atomistic simulations to study the resonant acoustic modes and compare different calculations of the acoustic mean-free path in amorphous systems with nanometric crystalline…
New insights on the high-pressure phase diagram of molecular CO2
Valentina M. Giordano, Frédéric Datchi
We report the discovery of a new molecular phase of carbon dioxide at high-pressure and high-temperature. Using x-ray diffraction, we identify this phase as the theoretically predi…
Melting curve and fluid equation of state of carbon dioxide at high pressure and high temperature
Valentina M. Giordano, Frédéric Datchi, Agnès Dewaele
The melting curve and fluid equation of state of carbon dioxide have been determined under high pressure in a resistively-heated diamond anvil cell. The melting line was determined…
