Methods for characterization of atomic-scale field emission point-electron-source
Shuai Tang, Mingkai Gou, Yingzhou Hu +7
Field emission (FE) electron sources are made close to atomic-scale to reach the highest spatial resolution as well as stable emission for electron microscopy, electron beam inspec…
Deep-Subwavelength Plasmon Polariton Atomic Cavity Detector for Frequency- and Polarization-Sensitive Terahertz Detection and Imaging
Shaojing Liu, Hongjia Zhu, Ximiao Wang +8
Room-temperature, miniaturized, polarization-resolved terahertz (THz) detection of high speed is vital for high-resolution imaging in radar, remote sensing, and semiconductor inspe…
Deep Learning Empowered Sub-Diffraction Terahertz Backpropagation Single-Pixel Imaging
Yongsheng Zhu, Shaojing Liu, Ximiao Wang +8
Terahertz single-pixel imaging (THz SPI) has garnered widespread attention for its potential to overcome challenges associated with THz focal plane arrays. However, the inherently…
Generalized Huang's Equation for Phonon Polariton in Polyatomic Polar Crystal
Weiliang Wang, Ningsheng Xu, Yingyi Jiang +4
The original theory of phonon polariton is Huang's equation which is suitable for diatomic polar crystals only. We proposed a generalized Huang's equation without fitting parameter…
