研究実績の概要

In this year, we have made several different shapes of holographic apertures by using e-beam lithography method. We have installed these apertures to the microscope condenser lens system to get preliminary results.
We have published 12 papers in total (Nature Communication, Science Advances, Advanced Materials, npj 2D Materials and Applications, ACS Nano, Advanced Science, Small, Chemistry of Materials, and etc.).
Three first author papers are with title of "Formation of highly doped nanostripes in 2D transition metal dichalcogenides via dislocation climb mechanism", "Two-dimensional Iodine-Monofluoride Epitaxy on WSe2", and "Scanning Moire Fringe Method: A superior approach to perceive defects, interfaces, and distortion in 2D materials".

理由

The focused ion beam service from companies and laboratories were limited due to the COVID-19, so we can only rely on the e-beam lithography to make holographic apertures. The holographic apertures was installed to our microscope CL system and the electron beam can pass through the holographic aperture. Because our TEM was not made for generating vortex beam when it was built, so the design of CL system was simple. We concluded that it will be necessary to modify the condenser lens system to get higher quality data. In order to select vortex electrons with higher order of angular momentum, we need to install additional aperture device which is a big task to limit the progress of this project.

今後の研究の推進方策

The modification of condenser lens (CL) is to install an extra selective CL aperture device which requires to open the microscope column and is not a simple task for a high-end delicate transmission electron microscope. This modification also requires several adjustment to find the best combination with the holographic aperture shape and the new selective CL aperture location.
We plan to proceed such CL modification in another spared microscope to test the selection of different angular momentum from the vortex beam.

次年度使用額が生じた理由

Due to the spread of COVID-19, the project was delayed due to the announcement of state of emergency. We were forced to work from home.
