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…
Precursor Selection in Hybrid Molecular Beam Epitaxy of Alkaline-Earth Stannates
Abhinav Prakash, Tianqi Wang, Rashmi Choudhary +3
One of the challenges of oxide molecular beam epitaxy (MBE) is the synthesis of oxides containing metals with high electronegativity (metals that are hard to oxidize). The use of r…
Unraveling the Effect of Electron-Electron Interaction on Electronic Transport in High-Mobility Stannate Films
Jin Yue, Laxman R. Thoutam, Abhinav Prakash +2
Contrary to the common belief that electron-electron interaction (EEI) should be negligible in s-orbital-based conductors, we demonstrated that the EEI effect could play a signific…
Separating Electrons and Donors in BaSnO3 via Band Engineering
Abhinav Prakash, Nicholas F. Quackenbush, Hwanhui Yun +9
Through a combination of thin film growth, hard X-ray photoelectron spectroscopy (HAXPES), scanning transmission electron microscopy/electron energy loss spectroscopy (STEM/EELS),…
Effects of paramagnetic pair-breaking and spin-orbital coupling on multi-band superconductivity
Yilikal Ayino, Jin Yue, Tianqi Wang +2
The BCS picture of superconductivity describes pairing between electrons originating from a single band. A generalization of this picture occurs in multi-band superconductors, wher…
