Atomic layer etching of niobium nitride using sequential exposures of O$_2$ and H$_2$/SF$_6$ plasmas

Posted by dbos Caltech

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Azmain A. Hossain, Sela Murphy, David S. Catherall, Anthony J. Ardizzi, Austin J. Minnich | Summary: Niobium nitride (NbN) is a metallic superconductor that is widely used for superconducting electronics due to its high transition temperature ($T_c$) and kinetic inductance. Processing-induced damage negatively affects the performance […]

Orbital Wigner functions and quantum transport in multiband systems

Posted by dbos Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Johannes Mitscherling, Dan S. Borgnia, SuryaNeil Ahuja, Joel E. Moore, Vir B. Bulchandani | Summary: Traditional theories of electron transport in crystals are based on the Boltzmann equation and do not capture physics arising from quantum coherence. We introduce a transport formalism based on ”orbital Wigner […]

Unveiling the Interfacial Reconstruction Mechanism Enabling Stable Growth of the Delafossite PdCoO2 on Al2O3 and LaAlO3

Posted by dbos Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Anna Scheid, Tobias Heil, Y. Eren Suyolcu, Qi song, Niklas Enderlein | Summary: Delafossites, comprised of noble metal (A+) and strongly correlated sublayers (BO2-), form natural superlattices with highly anisotropic properties. These properties hold significant promise for various applications, but their exploitation hinges on the successful […]

Bright hybrid excitons in molecularly tunable bilayer crystals

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Tomojit Chowdhury, Aurélie Champagne, Patrick Knüppel, Zehra Naqvi, Ariana Ray | Summary: Bilayer crystals, built by stacking crystalline monolayers, generate interlayer potentials that govern excitonic phenomena but are constrained by fixed covalent lattices and orientations. Replacing one layer with an atomically thin molecular crystal overcomes this […]
