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…
Thermopower modulation clarification of the intrinsic effective mass in a transparent oxide semiconductor, BaSnO3
Anup V. Sanchela, Takaki Onozato, Bin Feng +2
Although there are so many reports on the carrier effective mass (m*) of a transparent oxide semiconductor BaSnO3, it is almost impossible to know the intrinsic m* value because th…
Thermoelectric phase diagram of the SrTiO3-SrNbO3 solid solution system
Yuqiao Zhang, Bin Feng, Hiroyuki Hayashi +4
Thermoelectric energy conversion - the exploitation of the Seebeck effect to convert waste heat into electricity - has attracted an increasing amount of research attention for ener…
