Direct Visualization of Localized Vibrations at Complex Grain Boundaries
Eric R. Hoglund, De-Liang Bao, Andrew O'Hara +7
Grain boundaries (GBs) are a prolific microstructural feature that dominates the functionality of a wide class of materials. The change in functionality at a GB is a direct result…
Twisted bilayer zigzag-graphene nanoribbon junctions with tunable edge states
Dongfei Wang, De-Liang Bao, Qi Zheng +14
Stacking two-dimensional layered materials such as graphene and transitional metal dichalcogenides with nonzero interlayer twist angles has recently become attractive because of th…
Nanoscale Phonon Spectroscopy Reveals Emergent Interface Vibrational Structure of Superlattices
Eric R. Hoglund, De-Liang Bao, Andrew O'Hara +16
As the length-scales of materials decrease, heterogeneities associated with interfaces approach the importance of the surrounding materials. Emergent electronic and magnetic interf…
Atomically-Precise, Custom-Design Origami Graphene Nanostructures
Hui Chen, Xian-Li Zhang, Yu-Yang Zhang +8
The construction of atomically-precise carbon nanostructures holds promise for developing novel materials for scientific study and nanotechnology applications. Here we show that gr…
Intrinsically patterned two-dimensional materials for selective adsorption of molecules and nanoclusters
X Lin, JC Lu, Y Shao +23
Two-dimensional (2D) materials have been studied extensively as monolayers 1-5, vertical or lateral heterostructures 6-8. To achieve functionalization, monolayers are often pattern…
Atomic-Resolution Visualization and Doping Effects of Complex Structures in Intercalated Bilayer Graphene
Jason P. Bonacum, Andrew O'Hara, De-Liang Bao +9
Molecules intercalating two-dimensional (2D) materials form complex structures that have been mostly characterized by spatially averaged techniques. Here we use aberration-correcte…
