Anharmonic lattice dynamics and superconductivity in strained bulk and surface niobium
Mihir Ranjan Sahoo, Roman Lucrezi, Pedro Nunes Ferreira +5
Using first-principles calculations, we investigate how homogeneous strain and crystallographic surface orientation modify the vibrational and superconducting properties of niobium…
Vacancy-free cubic superconducting NbN enabled by quantum anharmonicity
Eva Kogler, Mihir R. Sahoo, Chia-Nien Tsai +10
Niobium nitride (NbN) is renowned for its exceptional mechanical, electronic, magnetic, and superconducting properties. The ideal 1:1 stoichiometric -NbN cubic phase, however, i…
Resonant phonons: Localization in a structurally ordered crystal
Albert Beardo, Paul Desmarchelier, Chia-Nien Tsai +3
Phonon localization is a phenomenon that influences numerous material properties in condensed matter physics. Anderson localization brings rise to localized atomic-scale phonon int…
Entropic signature of resonant thermal transport: Ordered form of heat conduction
Albert Beardo, Prajit Rawte, Chia-Nien Tsai +1
Thermal transport in crystals is influenced by chemistry, boundaries, and nanostructure. The anharmonic phonon band structure extracted from molecular-dynamics simulations provides…
Metaharvesting: Emergent energy harvesting by piezoelectric metamaterials
Ibrahim Patrick, Sondipon Adhikari, Mahmoud I. Hussein
Vibration energy harvesting is a technology that enables electric power generation by augmenting vibrating materials or structures with piezoelectric elements. In a recent work, we…
Vibronics of multi-material nanopillared membranes and impact on the thermal conductivity
Lina Yang, Mahmoud I. Hussein
Atomic motion in nanopillars standing on the surface of a silicon membrane generates vibrons, which are wavenumber-independent phonons that act as local resonances. These vibrons c…
