Latest - Shear banding mechanism in nanoceramic ZrN

The entire process of shear banding was observed in the nanocrystalline ceramic (NCC) nanopillars of ZrN. Results show that shear band forms in NCC through localized and cooperative granular activities involving nanocrack formation.

Conference Presentation - Environment-Dependent Electron Beam Reduction by Aram Yoon

Environmental transmission electron microscopy (ETEM) opens a new field for exploring dynamic behavior of the materials in-situ in response to varying experimental stimuli in TEM. The electron beam itself is included as a stimuli; electron interacts with the sample and the environment and thus electron probing of the reacting materials also increase the chance of driving the material far from its steady state reactions

Surface structure of etched β-Ga2O3

β-Ga2O3 with a bandgap of ∼4.6–4.9 eV and readily available bulk substrates, has attracted tremendous interest in the wide bandgap semiconductor community. However, its structure is complex and surface/interface state largely is unknown. In collaboration with Prof. Xiuling Li's group at ECE, Xun Zhan determined for the first time the surface structure of etched β-Ga2O3 using aberration corrected HAADF-STEM and ABF-STEM imaging.
