Hybrid BaTiO3/TiO2 Metasurface for Efficient Gigahertz-Speed Free-Space Electro-Optic Modulation
Zhongpeng Sun, Kerolos M. A. Yousef, Michael Domm +13
Free-space electro-optic modulators are key to emerging photonic systems, yet their performance remains limited by trade-offs between modulation efficiency, bandwidth, and device a…
Tunable Ferroelectric Acoustic Resonators in Monolithic Thin-Film Barium Titanate
Ian Anderson, Agham Posadas, Alexander A. Demkov +1
The increasing development of wireless communication bands has motivated the development of compact, low-loss, and frequency adjustable RF filtering technologies. Acoustic resonato…
Ultra-Low-Power Tuning in Hybrid Barium Titanate-Silicon Nitride Electro-Optic Devices on Silicon
J. Elliott Ortmann, Felix Eltes, Daniele Caimi +5
As the optical analogue to integrated electronics, integrated photonics has already found widespread use in data centers in the form of optical interconnects. As global network tra…
Quench dynamics of Anderson impurity model using configuration interaction method
Chungwei Lin, Alexander A. Demkov
We study the quench dynamics of an Anderson impurity model using the configuration interaction (CI) method. In particular, we focus on the relaxation behavior of the impurity occup…
Final-state effect on x-ray photoelectron spectrum of nominally and -doped transition metal oxides
Chungwei Lin, Agham Posadas, Tobias Hadamek +1
We investigate the x-ray photoelectron spectroscopy (XPS) of nominally and -doped transition metal oxides including NbO, SrVO, and LaTiO (nominally …
Electron Correlation in Oxygen Vacancy in SrTiO
Chungwei Lin, Alexander A. Demkov
Oxygen vacancies are an important type of defect in transition metal oxides. In SrTiO they are believed to be the main donors in an otherwise intrinsic crystal. At the same tim…
