My work in China began in July 2017 in Shanghai Institute of Optics and Fine Mechanics situated in Jiading, very green, beautiful and quiet part of Shanghai city. Since the research topic concerns special optical features of nanostructures, their study involved many methods of material preparation, characterization and optical probing. I met a cohesive team of scientists performing together investigations of two-dimensional nanostructures and development of new nonlinear optical materials and...
