Resonant Raman spectroscopies beyond density-functional theory
Aleksandr Poliukhin, Corto Babs Aubry, Lorenzo Bastonero +1
Resonant Raman spectroscopy probes, in a single measurement, how electrons and phonons couple in a material. Density-functional theory (DFT) typically reproduces well phonon freque…
Direct observation of strain and confinement shaping the hole subbands of Ge quantum wells
Enrico Della Valle, Arianna Nigro, Miki Bonacci +6
Germanium-silicon-germanium (Ge/SiGe) heterostructures have emerged as a promising platform for hole-spin quantum technologies and high-mobility electronics, where st…
Carrier mobilities and electron-phonon interactions beyond DFT
Aleksandr Poliukhin, Nicola Colonna, Francesco Libbi +2
Electron-phonon coupling is a key interaction that governs diverse physical processes such as carrier transport, superconductivity, and optical absorption. Calculating such interac…
Extraction of the self energy and Eliashberg function from angle resolved photoemission spectroscopy using the xARPES code
Thomas P. van Waas, Christophe Berthod, Jan Berges +3
Angle-resolved photoemission spectroscopy is a powerful experimental technique for studying anisotropic many-body interactions through the electron spectral function. Existing atte…
First-principles phonon physics using the Pheasy code
Changpeng Lin, Jian Han, Ben Xu +1
Parameter-free calculations of lattice dynamics from first principles have achieved significant progress in the past decades, with a wealth of applications in thermodynamics, phase…
Elastic Constants and Bending Rigidities from Long-Wavelength Perturbation Expansions
Changpeng Lin, Samuel Poncé, Francesco Macheda +2
Mechanical and elastic properties of materials are among the most fundamental quantities for many engineering and industrial applications. Here, we present a formulation that is ef…
Imaging heat transport in suspended diamond nanostructures with integrated spin defect thermometers
Valentin Goblot, Kexin Wu, Enrico Di Lucente +8
Among all materials, mono-crystalline diamond has one of the highest measured thermal conductivities, with values above 2000 W/m/K at room temperature. This stems from momentum-con…
Temperature-invariant heat conductivity from compensating crystalline and glassy transport: from the Steinbach meteorite to furnace bricks
Michele Simoncelli, Daniele Fournier, Massimiliano Marangolo +6
The thermal conductivities of crystals and glasses vary strongly and with opposite trends upon heating, decreasing in crystals and increasing in glasses. Here, we show--both with f…
Density-functional perturbation theory for one-dimensional systems: implementation and relevance for phonons and electron-phonon interactions
Norma Rivano, Nicola Marzari, Thibault Sohier
The electronic and vibrational properties and electron-phonon couplings of one-dimensional materials will be key to many prospective applications in nanotechnology. Dimensionality…
Extraordinary high room-temperature carrier mobility in graphene-WSe heterostructures
L. Banszerus, T. Ouaj, T. Sohier +16
High charge carrier mobilities play a fundamental role for high-frequency electronics, integrated optoelectronics as well as for sensor and spintronic applications, where device pe…
