Metal-organic Pulsed Laser Deposition for Complex Oxide Heterostructures
Jung-Woo Lee, Jieun Kim, Anthony L. Edgeton +21
Point defects in complex oxide thin films play a critical role in determining material properties but remain challenging to control with precision. This study introduces metal-orga…
Oxide two-dimensional electron gas with high mobility at room-temperature
Kitae Eom, Hanjong Paik, Jinsol Seo +6
The prospect of 2-dimensional electron gases (2DEGs) possessing high mobility at room temperature in wide-bandgap perovskite stannates is enticing for oxide electronics, particular…
Route to in situ synthesis of epitaxial Pr2Ir2O7 thin films guided by thermodynamic calculations
Lu Guo, Shun-Li Shang, Neil Campbell +4
In situ growth of pyrochlore iridate thin films has been a long-standing challenge due to the low reactivity of Ir at low temperatures and the vaporization of volatile gas species…
Controlling spin current polarization through non-collinear antiferromagnetism
T. Nan, C. X. Quintela, J. Irwin +20
The spin-Hall effect describes the interconversion of charge currents and spin currents, enabling highly efficient manipulation of magnetization for spintronics. Symmetry condition…
Epitaxial antiperovskite/perovskite heterostructures for materials design
Camilo X. Quintela, Kyung Song, Ding-Fu Shao +9
We demonstrate fabrication of atomically sharp interfaces between nitride antiperovskite MnGaN and oxide perovskites (LaSr)(AlTa)O (LS…
Spontaneous Hall Effect enhanced by local Ir moments in epitaxial PrIrO thin films
Lu Guo, Neil Campbell, Yongseong Choi +10
Rare earth pyrochlore Iridates (RE2Ir2O7) consist of two interpenetrating cation sublattices, the RE with highly-frustrated magnetic moments, and the Iridium with extended conducti…
