Journal ArticleDOI
Microstructure and ferroelectricity of BaTiO3 thin films on Si for integrated photonics
Kristy J. Kormondy,Youri Popoff,Marilyne Sousa,Felix Eltes,Daniele Caimi,Marta D. Rossell,Manfred Fiebig,Patrik Hoffmann,Patrik Hoffmann,Chiara Marchiori,Michael Reinke,Michael Reinke,Morgan Trassin,Alexander A. Demkov,Jean Fompeyrine,Stefan Abel +15 more
TL;DR: The strong dependence of the Pockels effect in BTO thin films on their microstructure is reported, and guidelines on how to engineer thin films with strong electro-optic response are provided, to provide a roadmap to fully exploit the linear electro- optic effect in novel hybrid oxide/semiconductor nanophotonic devices.
Journal ArticleDOI
Scavenging of oxygen from SrTiO3 during oxide thin film deposition and the formation of interfacial 2DEGs
Agham Posadas,Kristy J. Kormondy,Wei Guo,Patrick Ponath,Jacqueline Geler-Kremer,Tobias Hadamek,Alexander A. Demkov +6 more
TL;DR: In this article, the authors demonstrate by depositing a variety of metals (Ti, Al, Nb, Pt, Eu, and Sr) and measuring the in situ core level spectra of both the metal and the oxide, three distinct types of behavior occur in thin metal films on SrTiO3 (100).
Journal ArticleDOI
Quasi-two-dimensional electron gas at the epitaxial alumina/SrTiO3 interface: Control of oxygen vacancies
Kristy J. Kormondy,Agham-Bayan S Posadas,Thong Q. Ngo,Sirong Lu,Nicholas J. Goble,Jean Jordan-Sweet,Xuan P. A. Gao,David J. Smith,Martha R. McCartney,John G. Ekerdt,Alexander A. Demkov +10 more
TL;DR: In this article, the authors reported on the highly conductive layer formed at the crystalline γ-alumina/SrTiO3 interface, which is attributed to oxygen vacancies.
Journal ArticleDOI
Large positive linear magnetoresistance in the two-dimensional t 2g electron gas at the EuO/SrTiO3 interface
Kristy J. Kormondy,Lingyuan Gao,Xiang Li,Sirong Lu,Agham Posadas,Shida Shen,Maxim Tsoi,Martha R. McCartney,David J. Smith,Jianshi Zhou,L. L. Lev,Marius-Adrian Husanu,Vladimir N. Strocov,Alexander A. Demkov +13 more
TL;DR: This system offers an as-yet-unexplored route to pursue proximity-induced effects in the oxide two-dimensional t2g electron gas.
Journal ArticleDOI
Analysis of the Pockels effect in ferroelectric barium titanate thin films on Si(001)
Kristy J. Kormondy,Stefan Abel,Florian Fallegger,Youri Popoff,Patrick Ponath,Agham Posadas,Marilyne Sousa,Daniele Caimi,Heinz Siegwart,Emanuele Uccelli,Lukas Czornomaz,Chiara Marchiori,Jean Fompeyrine,Alexander A. Demkov +13 more
TL;DR: In this article, the authors report on the electro-optic response of BTO films deposited on Si by molecular beam epitaxy (MBE), and characterize the structure of these films by reflection high-energy electron diffraction and X-ray diffraction.
