Spalled barium titanate single crystal thin films for functional device applications
Prachi Thureja, Andrew W. Nyholm, Martin Thomaschewski +3
We report a scalable approach for fabricating single-crystal barium titanate (BTO) thin films through spalling from bulk substrates. Conventional thin film growth techniques often…

Numerical Analysis of Lensless Imaging with Active Metasurfaces and Single-Pixel Detectors
Julie Belleville, Prachi Thureja, Harry A. Atwater
We introduce a conceptual framework for a lensless imaging system which employs an active metasurface as a high-frequency, continuously tunable amplitude and phase modulation apert…
