Researchers from the University of Electro-Communications (Akira Sumiyoshi and Jun Nakamura) and Tohoku University (Kohei Yamasue and Yasuo Cho) have made a significant advancement in visualizing the local dipole moments at the semiconductor surface. This study offers unprecedented insights into the atomic-scale charge distribution and dipole configuration using a combination of the scanning nonlinear dielectric microscope (SNDM) and advanced density functional theory (DFT) calculations.
