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…
High Coupling Tunable Acoustic Resonators in Monolithic Barium Titanate
Ian Anderson, Agham Posadas, Alexander A. Demkov +1
The growing number of wireless communication bands has driven demand for compact, low-loss, and frequency adjustable RF filtering. Tunable acoustic resonators are well suited to ad…
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…
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 …
Magnetic anisotropy modulation of magnetite in Fe3O4/BaTiO3(100) epitaxial structures
C. A. F. Vaz, J. Hoffman, A. -B. Posadas +1
Temperature dependent magnetometry and transport measurements on epitaxial Fe3O4 films grown on BaTiO3(100) single crystals by molecular beam epitaxy show a series of discontinuiti…
