Improving the lifetime of aluminum-based superconducting qubits through atomic layer etching and deposition

Posted by klaurent Caltech

Kavli Affiliate: Oskar Painter | Summary:We present a dry surface treatment combining atomic layer etching and deposition (ALE and ALD) to mitigate dielectric loss in fully fabricated superconducting quantum devices formed from aluminum thin films on silicon. The treatment, performed as a final processing step prior to device packaging, starts by conformally removing the native […]

XHEMTs on Ultrawide Bandgap Single-Crystal AlN Substrates

Posted by klaurent Cornell

Kavli Affiliate: Grace Xing | Summary:AlN has the largest bandgap in the wurtzite III-nitride semiconductor family, making it an ideal barrier for a thin GaN channel to achieve strong carrier confinement in field-effect transistors, analogous to silicon-on-insulator technology. Unlike SiO$_2$/Si/SiO$_2$, AlN/GaN/AlN can be grown fully epitaxially, enabling high carrier mobilities suitable for high-frequency applications. However, […]

A genetic driver of epileptic encephalopathy impairs gating of synaptic glycolysis

Posted by dbos Rockefeller

Kavli Affiliate: Timothy A. Ryan | Authors: Zhanat Koshenov, Alexandros C. Kokotos, Lorena Benedetti, Jennifer Lippincott Schwartz and Timothy A. Ryan | Summary: The brain is a disproportionately large consumer of fuel, estimated to expend ∼20% of the whole-body energy budget, and therefore it is critical to adequately control brain fuel expenditures while satisfying its […]

A Bimodal Metallicity Distribution Function in the Ultra-Faint Dwarf Galaxy Reticulum II

Posted by klaurent MIT

Kavli Affiliate: Anna Frebel | Summary:Star formation in ultra-faint dwarf galaxies (UFDs, $M_* <10^5M_odot$) is suppressed by reionization, but may not be completely quenched. The metallicity distribution function (MDF) of stars in ultra-faint dwarf galaxies could show these signatures of reionization. However, past studies of UFD MDFs have been limited, because there are only a […]

Cosmic-ray and Interstellar Gas Properties in the Solar Neighborhood Revealed by Diffuse Gamma Rays

Posted by klaurent Stanford

Kavli Affiliate: Igor Moskalenko | Summary:To investigate the interstellar medium (ISM) and Galactic cosmic rays (CRs) in the solar neighborhood, we analyzed $γ$-ray data by Fermi Large Area Telescope (LAT) for five nearby molecular cloud regions. Our data includes the MBM/Pegasus region (MBM~53, 54, 55 clouds and Pegasus loop), R CrA region (R Coronae Australis […]
