Structural Commonalities in Amorphous Elemental Materials
I. Rodríguez, R. M. Valladares, A. Valladares +5
In the In recent times, the research community has explored diverse structures and novel fabrication methods for amorphous solids. This work investigates structural trends among di…
Edge-Dependent Superconductivity in Twisted Bismuth Bilayers
Isaías Rodríguez, Renela M. Valladares, Alexander Valladares +3
Twisted bilayers offer a compelling and, at times, confounding platform for the engineering of new twistronic materials. Whereas standard studies almost exclusively focus on the ex…
The Low-Temperature Electronic Specific Heats of Disordered Ag-Au Alloys, Revisited
David Hinojosa-Romero, Renela María Valladares, Alexander Valladares +2
Disordered alloys of silver and gold have been in the interest of the condensed matter community for decades since they are the prototype of the ideal solid solution due to the che…
Amorphous Boron Nitride: Ab initio Study of its vibrational properties
David Hinojosa-Romero, Alexander Valladares, Renela M. Valladares +2
Boron nitride (BN) is a structurally versatile insulator since it can be found in several crystalline structures with interesting mechanical and electrical properties, making this…
Short-range Atomic Topology of Ab initio Generated Amorphous PdSi Alloys
Isaías Rodríguez-Aguirre, Renela M. Valladares, Alexander Valladares +2
Since the pioneering efforts of Duwez and coworkers in 1965, when a solid amorphous phase of Pd-Si (-PdSi) was obtained in the vicinity of the eutectic concentration, much work…
\textit{Ab initio} Studies of Magnetism and Topology in solid Pd-rich a-PdSi Alloys
Isaías Rodríguez, Renela M. Valladares, Alexander Valladares +2
In 1965 Duwez \textit{et al.} reported having generated an amorphous, stable phase of palladium-silicon in the region 15 to 23 atomic percent (at. \%) silicon. These pioneering eff…
