Outline of Final Research Achievements

We have deepened our understanding of the theory behind creating an electron vortex beam in TEM. Fork-type apertures were fabricated to generate vortex electrons. Adding a phase aperture to TEM would require modifications to the electron optics and a larger budget to accomplish. Nevertheless, with the support of this project, we have studied various aspects of two-dimensional materials such as doping, intercalation, phase transformation, and superlattice structure. Over the past 5 years, we have published 34 papers, including articles in high-impact journals such as Nature, Nature Materials, Advanced Materials, ACS Nano, and Nano Letters, thanks to the support of this funding.
