AlVO thin films via in-situ interfacial topotaxy
Jeong Rae Kim, Alexis Ashby, Sandra Glotzer +3
Conventional oxide epitaxy approaches face challenges when the oxidation conditions of constituent elements differ significantly. Here we demonstrate that V--O thin films can serve…
Identification of the I Donor in ZnO as a Sn--Li Complex with Large Hyperfine Interaction
Xingyi Wang, Sai Mu, Jeong Rae Kim +6
Donor impurities in wide direct band gap semiconductors provide a promising platform for spin--photon quantum technologies by combining a donor spin qubit with optically addressabl…
Thermally-Activated Epitaxy of NbO
Sandra Glotzer, Jeong Rae Kim, Joseph Falson
We demonstrate a thermally-activated epitaxy window for the growth of NbO at temperatures exceeding 1000 C. NbO films grown in this mode display superior structural and transpo…
Superconducting vacancy-ordered rock-salt NbO films
Jeong Rae Kim, Sandra Glotzer, Evan Krysko +5
We report molecular beam epitaxy synthesis of vacancy-ordered rocksalt NbO thin films which display superconductivity. A comparative study of substrates identifies AlO (000…
High temperature diffusion enabled epitaxy of the Ti-O system
Jeong Rae Kim, Sandra Glotzer, Adrian Llanos +2
High temperatures promote kinetic processes which can drive crystal synthesis towards ideal thermodynamic conditions, thereby realizing samples of superior quality. While accessing…
