Suppression of Superconductivity and Electrostatic Side Gate Tuning in High Mobility SrTiO Surface Electron Gas
Dickson Boahen, Sushant Padhye, Gayan De Silva +2
We report on the fabrication and characterization of patterned high-mobility two-dimensional electron gases (2DEG) formed on SrTiO (STO) substrate surfaces by hydrogen plasma e…

Superconducting Dome in Ionic Liquid Gated Homoepitaxial Strontium Titanate Thin Films
Sushant Padhye, Jin Yue, Shivasheesh Varshney +3
In this work, we patterned a two-dimensional electron gas (2DEG) on the surface of a SrTiO thin film grown homoepitaxially on SrTiO by hybrid molecular beam epitaxy (hMBE).…

α-Ta (111) Thin Films for Qubit Applications: A Study of Thickness Dependence and Universal Scaling
Nate Price, Jose Gutiérrez, Sushant Padhye +8
We explore the growth of α-Ta thin films ranging from ultra-thin (2 nm) to thick (250 nm) films grown by sputter epitaxy on c-plane sapphire substrates. We utilized 100 W power wi…
