Coherent consolidation of trillions of nucleations for mono-atom step-level flat surfaces - Nature Communications Constructing atomically flat surface in a single crystal ultrathin film is difficult owing to the coherent merging of trillions of clusters. Here the authors establish the initial growth mechanism of a single crystal Cu thin film with atomically flat surface using atomic sputtering epitaxy.

Subwavelength Terahertz Resonance Imaging (STRING) for Molecular Fingerprinting Subwavelength terahertz (THz) imaging methods are highly desirable for biochemical sensing as well as materials sciences, yet sensitive spectral fingerprinting is still challenging in the frequency domain due to weak light–matter interactions. Here, we demonstrate subwavelength THz resonance imagi...

Controlling Spin–Orbit Coupling to Tailor Type-II Dirac Bands NiTe2, a type-II Dirac semimetal with a strongly tilted Dirac band, has been explored extensively to understand its intriguing topological properties. Here, using density functional theory calculations, we report that the strength of the spin–orbit coupling (SOC) in NiTe2 can be tuned by Se substi...
