Title: Japanese research in Nanotechnology: Kyoto University and Yokohama City University research topics and applications

I will give an introduction to the topics I am involved in my research in Japan. Three main research themas will be described. The first will concern the study of unstable optical emission in solid state Indium Gallium Nitride materials. These materials are used to realize LEDs and Lasers. I will describe the structure of these samples, how they work and their peculiar, unstable optical properties. We also study the Quantum Dots present in these optical material with special polarization modulation techniques. I will describe the experimental method as well as the intriguing results obtained on Indium Gallium Nitride materials. Finally I will give a brief introduction to life-science related topics, that are recently taking more and more importance in the Japanese scientific scene.
