Scanning probe, Optics, Low dimensional quantum materials

The ability to simultaneously collect an optical spectrum and topographic information at the nanosize pixel step provides critical insight into understanding how local material properties and structure result in the macroscopic functionality of a material. The near-field optics lab, led by Dr. Alex Weber-Bargioni, is equipped with the AIST-NT scanning probe system, which has optical access from the top, side, and bottom of the scanning stage.  We also fabricate our own scanning probe based on fiber using the high throughput nanoimprinting method developed in nanofabrication facilities. Currently, I apply this homemade tip for studying the exciton-plasmon coupling effects.
