Accurate Nanoscale Mapping of Electric Fields across Random Grain Boundaries in Polycrystalline Oxides Using Precession-Assisted 4D-STEM
Sangjun Kang, Hyeyoung Cho, Maximilian Töllner +12
Space charge layers (SCLs) at grain boundaries play a crucial role in modulating local electric fields and influencing the functional properties of materials, such as oxygen vacanc…
Impact of charge transition levels on grain boundary properties in acceptor doped oxide ceramics: A phase-field study
Kai Wang, Sangjun Kang, Mahmoud Serour +8
Advanced doping strategies enable oxide ceramic functionalities by tailoring bulk defect chemistry and space-charge-layer (SCL) behavior at interfaces. Charge transition levels (CT…
Enhanced Charge-Density-Wave Order and Suppressed Superconductivity in Intercalated Bulk
Huanhuan Shi, Qili Li, Antoine M. T. Baron +12
The electronic ground states of transition-metal dichalcogenides are strongly shaped by reduced dimensionality, yet the properties of atomically thin layers remain difficult to pro…
Simultaneous mapping of magnetic and atomic structure for direct visualization of nanoscale magnetoelastic coupling
Sangjun Kang, Maximilian Töllner, Di Wang +7
Achieving a correlative measurement of both magnetic and atomic structures at the nanoscale is imperative to understand the fundamental magnetism of matters and for fostering the d…
