Chiral, Electronically Decoupled Layers of 1T'-WS2 Topological Insulator via Neutral-Molecule Intercalation
Jiaze Xie, Fatmagül Katmer, Fang Yuan +9
Monolayer 1T'-WS2 is predicted to be a two-dimensional topological insulator, but its intrinsic electronic properties are masked by strong interlayer coupling in its metallic and s…
Mechanochemical Nano-Writing of an Atomically Thin Metal
Shuai Zhang, Yanyu Jia, Atanu Samanta +14
Mechanical energy accelerates many physicochemical processes, including materials syntheses that are hard to produce with thermal energy alone. However, physical understanding conn…
Directionally Locked Heteroepitaxy with a Structurally Modulated van der Waals Material
Nitish Mathur, Guangming Cheng, Francesc Ballester +17
Precise orientation of symmetry-mismatched epilayers on van der Waals (vdW) substrates via heteroepitaxy has commonly been achieved through surface treatment processes to accommoda…
Quantifying surface losses in superconducting aluminum microwave resonators
Elizabeth Hedrick, Faranak Bahrami, Alexander C. Pakpour-Tabrizi +11
The recent realization of millisecond-scale coherence with tantalum-on-silicon transmon qubits showed that depositing the Al/AlOx/Al Josephson junction in a high purity, ultrahigh…
Beta Tantalum Transmon Qubits with Quality Factors Approaching 10 Million
Atharv Joshi, Apoorv Jindal, Paal H. Prestegaard +9
Tantalum-based transmon qubits are a promising platform for building large-scale quantum processors. So far, these qubits have been made from tantalum films grown exclusively in th…
Superconducting Gap Engineering in Tantalum-Alloy-Based Resonators
Chen Yang, Faranak Bahrami, Guangming Cheng +7
Utilizing tantalum (Ta) in superconducting circuits has led to significant improvements, such as high qubit lifetimes and quality factors in both qubits and resonators, underscorin…
