Gate-tunable electronic properties of epitaxial Bi (111) films using a printable hexagonal boron nitride ionogel
Jagannath Jena, Heather E. Kurtz, Siddhesh Ambhire +9
Achieving effective electrostatic control of carrier transport in semimetals remains challenging due to strong screening and multiband effects. We report efficient low voltage top…
The Role of Defect Geometry in Localized Emission from Monolayer Tungsten Dichalcogenides
S. Carin Gavin, Moumita Kar, Jianguo Wen +10
Understanding the mechanism of single photon emission (SPE) in two-dimensional (2D) material is an unsolved problem important for quantum optical materials and the development of q…
Millimeter-Scale, Atomically Controlled 2D Topological Insulators Revealed by Multimodal Spectroscopy
Woojoo Lee, Qiang Gao, Yufei Zhao +20
Quantum spin Hall insulators, or synonymously known as 2D topological insulators, are crucial 2D systems hosting topologically protected edge states. The working temperature of thi…
A Surface-Scaffolded Molecular Qubit
Tian-Xing Zheng, M. Iqbal Bakti Utama, Xingyu Gao +24
Fluorescent spin qubits are central building blocks of quantum technologies. Placing these qubits at surfaces maximizes coupling to nearby spins and fields, enabling nanoscale sens…
Comparison of Nb and Ta Pentoxide Loss Tangents for Superconducting Quantum Devices
D. P. Goronzy, W. W. Mah, P. G. Lim +14
Superconducting transmon qubits are commonly made with thin-film Nb wiring, but recent studies have shown increased performance with Ta wiring. In this work, we compare the resonat…
Robust interpretation of electrochemical impedance spectra using numerical complex analysis
Jithin D. George, Willa Brenneis, Vinod K. Sangwan +9
Electrochemical Impedance Spectroscopy (EIS) is a non-invasive technique widely used for understanding charge transfer and charge transport processes in electrochemical systems and…
