Electron Accumulation and Emergent Magnetism in LaMnO3/SrTiO3 Heterostructures
Zuhuang Chen, Zhanghui Chen, Z. Q. Liu +19
Emergent phenomena at polar-nonpolar oxide interfaces have been studied intensely in pursuit of next-generation oxide electronics and spintronics. Here we report the disentanglemen…
Self-Assembled, Nanostructured, Tunable Metamaterials via Spinodal Decomposition
Zuhuang Chen, Xi Wang, Yajun Qi +9
Self-assembly via nanoscale phase-separation offers an elegant route to fabricate nanocomposites with physical properties unattainable in single-component systems. One important cl…
Nanosecond Phase Transition Dynamics in Compressively Strained Epitaxial BiFeO3
Margaret P. Cosgriff, Pice Chen, Sung Su Lee +11
A highly strained BiFeO3 (BFO) thin film is transformed between phases with distinct structures and properties by nanosecond-duration applied electric field pulses. Time-resolved s…
180 degree Ferroelectric Stripe Nanodomains in BiFeO3 Thin Films
Zuhuang Chen, Jian Liu, Yajun Qi +7
There is growing evidence that domain walls in ferroics can possess emergent properties that are absent in bulk materials. For example, 180 domain walls in the ferroelectric-antife…
Unit cell determination of epitaxial thin films based on reciprocal space vectors by high-resolution X-ray diffractometry
Ping Yang, Huajun Liu, Zuhuang Chen +2
A new approach, based on reciprocal space vectors (RSVs), is developed to determine Bravais lattice types and accurate lattice parameters of epitaxial thin films by high-resolution…
Periodic elastic nanodomains in ultrathin tetrogonal-like BiFeO3 films
Zhenlin Luo, Zuhuang Chen, Yuanjun Yang +14
We present a synchrotron grazing incidence x-ray diffraction analysis of the domain structure and polar symmetry of highly strained BiFeO3 thin films grown on LaAlO3 substrate. We…
Large tensile strain induced monoclinic MB phase in BiFeO3 epitaxial thin films on PrScO3 substrate
Zuhuang Chen, Yajun Qi, Lu You +5
Crystal and domain structures of tensile-strained BiFeO3 films grown on orthorhombic (110)o PrScO3 substrates were investigated. All films possess a MB-type monoclinic structure wi…
Study of strain effect on in-plane polarization in epitaxial BiFeO3 thin films using planar electrodes
Zuhuang Chen, Xi Zou, Wei Ren +8
Epitaxial strain plays an important role in determining physical properties of perovskite ferroelectric oxide thin films. However, it is very challenging to directly measure proper…
Domain tuning in mixed-phase BiFeO3 thin films using vicinal substrates
Lu You, Shintaro Yasui, Xi Zou +6
The structural and ferroelectric domain variants of highly-strained BiFeO3 films grown on vicinal LaSrAlO4 substrates were studied by piezoelectric force microscopy and high-resolu…
Temperature-driven evolution of hierarchical nanodomain structure in tetragonal-like BiFeO3 films
Yajun Qi, Zuhuang Chen, Lihua Wang +4
Transmission electron microscopy study of tetragonal-like BiFeO3 films reveals a hitherto unreported hierarchical nanodomain structure. The 30-50 nm wide stripe domains with {110}…
Characterization and manipulation of mixed phase domains in highly-strained BiFeO3 thin films
Lu You, Zuhuang Chen, Xi Zou +5
The novel strain-driven morphotropic phase boundary (MPB) in highly-strained BiFeO3 thin film is featured by ordered mixed phase nanodomains (MPNs). Through scanning probe microsco…
Coexistence of Ferroelectric Triclinic Phases and Origin of Large Piezoelectric Responses in Highly Strained BiFeO3 films
Zuhuang Chen, S. Prosandeev, Z. L. Luo +12
The structural evolution of the strain-driven morphotropic phase boundary (MPB) in BiFeO3 films has been investigated using synchrotron x-ray diffractometry in conjunction with sca…
