Complementary Vanadium Dioxide Metamaterials with Enhanced Modulation Amplitude at Terahertz Frequencies

Autor: Huang, Yuwei, Wu, Xuefei, Schalch, Jacob, Duan, Guangwu, Chen, Chunxu, Zhao, Xiaoguang, Kaj, Kelson, Zhang, Hai-Tian, Engel-Herbert, Roman, Averitt, Richard D., Zhang, Xin

One route to create tunable metamaterials is through integration with "on-demand" dynamic quantum materials, such as vanadium dioxide (VO2). This enables new modalities to create high performance devices for historically challenging applications. Ind

Proton distribution visualization in perovskite nickelate devices utilizing nanofocused X-rays

Publikováno v: Phys. Rev. Materials 5, 095003 (2021)

We use a 30-nm x-ray beam to study the spatially resolved properties of a SmNiO$_3$-based nanodevice that is doped with protons. The x-ray absorption spectra supported by density-functional theory (DFT) simulations show partial reduction of nickel va
