Kohda Lab will welcome Ayumi Ishii ( Associate Professor of Waseda University, School of Advanced Science and Engineering ).

Title : “One-dimensional Helical Materials that Manipulate Light and Spin”

Lecturer : Ayumi Ishii  (Associate Professor Waseda University, School of Advanced Science and Engineering)

Date : 3:00 p.m. – 4:30 p.m. on Tuesday, March 18, 2025

Venue : Lecture Room 2(Room 102),1st Floor Materials Science and Engineering Education and Research Bldg. (B01)

In the context of human resource development and research and development in the domains of semiconductors and spintronics, it is imperative to establish and maintain connections with the global community. Active engagement in international brain circulation is identified as a pivotal aspect of this endeavor.
The necessity of cultivating young researchers who will assume active roles on the global stage, in addition to the pursuit of research through international collaboration, is a subject that is addressed in this discourse.

”Synchronized Photoluminescence and Electrical Mobility Enhancement in 2D WS2 through Sequence-Specific Chemical Passivation” was posted.

In an international collaboration with Uppsala University and Cambridge University, we have developed a new method to passivate defects by continuously chemically modifying the surface of the 2D material WS2. This makes it possible to increase both luminescence efficiency and mobility by a factor of 100.
