Occurrence of the collective Ziman limit of heat transport in cubic semiconductors Si, Ge, AlAs and AlP: scattering channels and size effects
Autor: Jelena Sjakste, Maxime Markov, Raja Sen, Giorgia Fugallo, Lorenzo Paulatto, Nathalie Vast
Publikováno v: Nano Express, Vol 5, Iss 3, p 035018 (2024)
In this work, we discuss the possibility of reaching the Ziman conditions for collective heat transport in cubic bulk semiconductors, such as Si, Ge, AlAs and AlP. In natural and enriched silicon and germanium, the collective heat transport limit is

Autor: Mizanur Rahman, Khaled Parvez, Giorgia Fugallo, Chaochao Dun, Oliver Read, Adriana Alieva, Jeffrey J. Urban, Michele Lazzeri, Cinzia Casiraghi, Simone Pisana
Publikováno v: Nanomaterials, Vol 12, Iss 21, p 3861 (2022)
Two-dimensional (2D) materials are uniquely suited for highly anisotropic thermal transport, which is important in thermoelectrics, thermal barrier coatings, and heat spreaders. Solution-processed 2D materials are attractive for simple, low-cost, and

A computational exploration of the interactions of the green tea polyphenol (-)-Epigallocatechin 3-Gallate with cardiac muscle troponin C.
Autor: Dominic Botten, Giorgia Fugallo, Franca Fraternali, Carla Molteni
Publikováno v: PLoS ONE, Vol 8, Iss 7, p e70556 (2013)
Thanks to its polyphenols and phytochemicals, green tea is believed to have a number of health benefits, including protecting from heart disease, but its mechanism of action at the molecular level is still not understood. Here we explore, by means of

Room temperature second sound in cumulene
Autor: Claudio Melis, Luciano Colombo, Giorgia Fugallo
Publikováno v: Physical Chemistry Chemical Physics
Physical Chemistry Chemical Physics, Royal Society of Chemistry, 2021, ⟨10.1039/d1cp00501d⟩
Second sound is known as the thermal transport regime occurring in a wave-like fashion, usually identified in a limited number of materials only at cryogenic temperatures. Here we show that second sound in a μm-long carbon chain (cumulene) might occ

Probing Ultrafast Dynamics of Anharmonically Coupled Phonons in Few-Layer Hexagonal Boron Nitride
Autor: Taehee Kang, Jia Zhang, Achintya Kundu, Klaus Reimann, Michael Woerner, Thomas Elsaesser, Bernard Gil, Guillaume Cassabois, Christos Flytzanis, Giorgia Fugallo, Michele Lazzeri, Ryan Page, Debdeep Jena
Publikováno v: Conference on Lasers and Electro-Optics.
Nonequilibrium dynamics of transverse optical (TO) phonons in few-layer hexagonal boron nitride is studied in mid-infrared pump-probe experiments. TO phonons display a 1.2 ps lifetime and a transient redshift due to anharmonic coupling with low-frequ

Electronic Structure, 2021, 3 (1), pp.014005. ⟨10.1088/2516-1075/abdb3c⟩
Exciton band structures analysis provides a powerful tool to identify the exciton character of materials, from bulk to isolated systems, and goes beyond the mere analysis of the optical spectra. In this work, we focus on the exciton properties of mol
