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

Acoustic graphene plasmons are superior to the graphene surface plasmons in field confinement and normalized propagation length, thus promising for applications. Here, the authors report near-field imaging of acoustic plasmons in high-quality CVD gra

High-quality, single-crystal-like Cu2O thin films of various thicknesses (10 nm–45 nm) were prepared at a low temperature (150 °C) by controlling layer-by-layer oxidation of wafer-scale Cu thin films sputtered along the (111) direction using a pur

Metamaterial memory devices often require a large stimulus to switch states or suffer from poor thermal stability. Here, the authors fabricate a terahertz metadevice driven by ferroelectric and graphene layers, and obtain multiple level memory device

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,

Anisotropic materials with chirality or birefringence can be used to manipulate the polarization states of electromagnetic waves. However, the comparatively low anisotropy of natural materials hinders the miniaturization of optical components and dev

Chiral fermions (CFs) in condensed matters, distinguished by right (+) or left (−) handedness, hold a promise for emergent quantum devices. Although a chiral anomaly induced current, J chiral = J (+) − J (−), occurs in Weyl semimetals due to th
