Development of a Scalable Quantum Memory Platform -- Materials Science of Erbium-Doped TiO Thin Films on Silicon
Manish Kumar Singh, Gary Wolfowicz, Jianguo Wen +6
Rare-earth ions (REI) have emerged as an attractive candidate for solid-state qubits, particularly as a quantum memory. Their 4f-4f transitions are shielded by filled 5s and 5p orb…
Direct observation and consequences of dopant segregation inside and outside dislocation cores in perovskite BaSnO3
Hwanhui Yun, Abhinav Prakash, Turan Birol +2
Distinct dopant behaviors inside and outside dislocation cores are identified by atomic-resolution electron microscopy in perovskite BaSnO3 with considerable consequences on local…
Surface state at evidenced by angle-resolved photoemission spectroscopy and ab initio calculations
Muntaser Naamneh, Abhinav Prakash, Eduardo B. Guedes +5
Perovskite alkaline earth stannates, such as and , showing light transparency and high electrical conductivity (when doped), have become promising candidates for…
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…
Electronic Structure and Small Hole Polarons in YTiO3
Jin Yue, Nicholas F. Quackenbush, Iflah Laraib +10
As a prototypical Mott insulator with ferromagnetic ordering, YTiO3 (YTO) is of great interest in the study of strong electron correlation effects and orbital ordering. Here we rep…
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…
STEM beam channeling in BaSnO3/LaAlO3 perovskite bilayers and visualization of 2D misfit dislocation network
Hwanhui Yun, Abhinav Prakash, Bharat Jalan +2
A study of the STEM probe channeling in a heterostructures crystalline specimen is presented here with a goal to guide appropriate STEM-based characterization for complex structure…
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),…
Electronic structure of BaSnO3 investigated by high-energy-resolution electron energy-loss spectroscopy and ab initio calculations
Hwanhui Yun, Mehmet Topsakal, Abhinav Prakash +6
There has been growing interest in perovskite BaSnO3 due to its desirable properties for oxide electronic devices including high electron mobility at room temperature and optical t…
Band alignment at epitaxial BaSnO3/SrTiO3(001) and BaSnO3/LaAlO3(001) heterojunctions
Scott A. Chambers, Tiffany C. Kaspar, Abhinav Prakash +2
We have spectroscopically determined the band offsets at epitaxial interfaces of BaSnO3 with SrTiO3(001) and LaAlO3(001). The conduction band minimum is lower in electron energy in…
