Millimeter-Scale, Atomically Controlled 2D Topological Insulators Revealed by Multimodal Spectroscopy

Abstract Quantum spin Hall insulators, also known as 2D topological insulators, are crucial 2D systems hosting topologically protected edge states. The working temperature of this topological quantum phase is dictated by the inverted bandgap. However, the previously identified la...

Oxide-Nitride Heteroepitaxy for Low-Loss Dielectrics in Superconducting Quantum Circuits

Abstract Superconducting qubits show great promise for the realization of fault-tolerant quantum computing, but lossy, amorphous dielectrics limit current technology. Identifying highly crystalline and stoichiometric dielectrics with intrinsically low microwave loss is therefore...

Assessing and EnhancingBase Bath Safety Culture ThroughStudent-Led Initiatives in an Academic Research Environment

Abstract Base baths, which typically employ strong bases dissolved in alcohols, are frequently used to clean laboratory glassware but present significant fire, chemical, and handling hazards when improperly prepared or maintained. This work evaluates prior awareness, documentatio...
