Hybrid Molecular Beam Epitaxy of Ge-based Oxides
Fengdeng Liu, Tristan K Truttmann, Dooyong Lee +6
Germanium-based oxides such as rutile GeO2 are garnering attention owing to their wide band gaps and the prospects for ambipolar doping for application in high-power devices. Here,…
Hysteretic Magnetoresistance in a Non-Magnetic SrSnO3 Film via Thermal Coupling to Dynamic Substrate Behavior
Laxman Raju Thoutam, Tristan K. Truttmann, Anil Kumar Rajapitamahuni +1
Hysteretic magnetoresistance (MR) is often used as a signature of ferromagnetism in conducting oxide thin films and heterostructures. Here, magnetotransport is investigated in a no…
Strain Relaxation via Phase Transformation in SrSnO3
Tristan K Truttmann, Fengdeng Liu, Javier Garcia Barriocanal +2
SrSnO3 (SSO) is an emerging ultra-wide bandgap (UWBG) semiconductor with potential for highpower applications. In-plane compressive strain was recently shown to stabilize the high…
Self-Assembled Periodic Nanostructures Using Martensitic Phase Transformations
Abhinav Prakash, Tianqi Wang, Ashley Bucsek +11
We describe a novel approach for the rational design and synthesis of self-assembled periodic nanostructures using martensitic phase transformations. We demonstrate this approach i…
Machine Learning Analysis of Perovskite Oxides Grown by Molecular Beam Epitaxy
Sydney R. Provence, Suresh Thapa, Rajendra Paudel +4
Reflection high-energy electron diffraction (RHEED) is a ubiquitous in situ molecular beam epitaxial (MBE) characterization tool. Although RHEED can be a powerful means for crystal…
Dopant Solubility, and Charge Compensation in La-doped SrSnO3 Films
Tristan Truttmann, Abhinav Prakash, Jin Yue +2
We investigate lanthanum (La) as an n-type dopant in the strain-stabilized tetragonal phase of SrSnO3 grown on GdScO3 (110) using a radical-based hybrid molecular beam epitaxy appr…
