High Upper Critical Field and Type II Superconductivity in Epitaxial Cubic W 2 N Thin Films

Aditya Singh, Arnaud le Febvrier, Sanath Kumar Honnali, Abhisek Mishra et autres

ABSTRACT Transition Metal Nitrides (TMNs) are a versatile class of materials, combining chemical robustness, high hardness, and superconducting behaviour with critical temperatures between 2–10 K. While several binary TMNs have been explored, superconductivity in stoichiometric W 2 N has remained largely unexplored. …

Interfacial Engineering of Dual‐Layer Au‐Shelled Ag Nanowires: Decoupling Chemical Stability From Ultrasensitive Surface‐Enhanced Raman Spectroscopy Activity

Yuyang Li, Mohammad Javad Jafari, Dongqing Lin, Justinas Pališaitis et autres

One‐dimensional (1D) silver nanowires are promising surface‐enhanced Raman spectroscopy (SERS) substrates, yet their plasmonic hotspots are spatially confined to sharp tips or junctions, leaving the extensive body optically inactive. Additionally, realizing high‐performance Ag‐based substrates faces a fundamental trade‐off between chemical stability and …

Low‐Temperature‐Sputtered Epitaxial WO 3 Bottom Electrodes for Reliable Interfacial Memristive and Neuromorphic Devices

Babak Bakhit, Abin Varghese, Simon M. Fairclough, Atif Jan et autres

Advances in emerging non‐volatile memories demand electrode materials that are complementary‐metal‐oxide‐semiconductor (CMOS) compatible and form atomically smooth, chemically well‐defined interfaces while enabling controlled interfacial oxygen exchange with switching layers. However, few materials simultaneously satisfy these requirements. Here, we demonstrate back‐end‐of‐line (BEOL) compatible, …
