Instability-driven mechanically locked states in functional oxide membranes
Varun Harbola, Thomas Emil le Cozannet, Denis Alikin +10
Mechanical instabilities in thin solids offer a powerful route to engineer nonlinear responses, yet their controlled use in functional crystalline oxides has remained largely unexp…
Adsorption-controlled Growth of Homoepitaxial c-plane Sapphire Films
Lena N. Majer, Tolga Acartürk, Peter A. van Aken +13
Sapphire is a technologically highly relevant material, but it poses many challenges to performing epitaxial thin-film deposition. We have identified and applied the conditions for…
alpha-Ta Films on c-plane Sapphire with Enhanced Microstructure
Lena N. Majer, Sander Smink, Wolfgang Braun +7
Superconducting films of alpha-Ta are promising candidates for the fabrication of advanced superconducting qubits. However, alpha-Ta films suffer from many growth-induced structura…
Vector-substrate-based Josephson junctions
Yu-Jung Wu, Martin Hack, Katja Wurster +5
We present a way to We present a way to fabricate bicrystal Josephson junctions of high-Tc cuprate superconductors that does not require bulk bicrystalline substrates. Based on vec…
