Based on a suitable band structure, the synergistic effect of oxygen vacancy defects and an electromagnetic field facilitates electron transfer. This process thereby achieves broadband absorption ...
Fig. 1. (a) THz optical path diagram based on metasurface. By controlling the phase delays of LCP and RCP waves by unit cells, metasurface can transmit the LCP and RCP components of the incident ...

Wave-like domain walls drive polarization switching in sliding ferroelectrics, study finds
Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, ...
Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...
