Atomic-environment-dependent thickness of ferroelastic domain walls
Mingqiang Li, Xiaomei Li, Yuehui Li +3
Domain walls are of increasing interest in ferroelectrics because of their unique properties and potential applications in future nanoelectronics. However, the thickness of ferroel…
Atomic-Scale Structure Relaxation, Chemistry and Charge Distribution of Dislocation Cores in SrTiO3
Peng Gao, Ryo Ishikawa, Bin Feng +3
By using the state-of-the-art microscopy and spectroscopy in aberration-corrected scanning transmission electron microscopes, we determine the atomic arrangements, occupancy, eleme…
Picometer-scale atom position analysis in annular bright-field STEM imaging
Peng Gao, Akihito Kumamoto, Ryo Ishikawa +3
We study the effects of specimen mistilt on the picometer-scale measurement of local structure by combing experiment and simulation in annular bright-field scanning transmission el…
Structural Changes Related to the Magnetic Transitions in Hexagonal InMnO3
T. Yu, T. A. Tyson, P. Gao +4
Two magnetic ordering transitions are found in InMnO3, the paramagnetic to antiferromagnetic transition near ~118 K and a lower possible spin rotation transition near ~42 K. Multip…
Ferroelectricity in Single Crystal InMnO3
T. Yu, P. Gao, T. Wu +2
Single crystal synthesis, structure, electric polarization and heat capacity measurements on hexagonal InMnO3 show that this small R ion in the RMnO3 series is ferroelectric (space…
High carrier mobility in transparent Ba1-xLaxSnO3 crystals with a wide band gap
X. Luo, Y. S. Oh, A. Sirenko +4
We discovered that perovskite (Ba,La)SnO3 can have excellent carrier mobility even though its band gap is large. The Hall mobility of Ba0.98La0.02SnO3 crystals with the n-type carr…
