Русский Welcome to Technology Resource Center “Nanofabrication of Photoactive Materials (Nanophotonics)” of St.Petersburg State University.
The main challenges of the "Nanofabrication of Photoactive Materials (Nanophotonics)" Resource Center are the development, creation and rapid testing of photoactive nanocomposite materials and elements for the following areas: optical and quantum supercomputers, nanoelectronics and micromechanics, solar power and photocatalysis, photoactive nanocoatings and sensors.
The Resource Center has a wide range of equipment and developed techniques for creating semiconductor quantum heterostructures by molecular beam epitaxy via SVTA MBE-35-3 unit with their subsequent optical characterization. Stands for the study of heterostructures by methods of four-wave mixing and resonance exciton reflection are available. In the center, it is possible to carry out optical and electronic lithography, to perform ion and plasma etching, to study the surface quality of samples using Atomic Force Microscopy (AFM) and Scanning Electron Microscopy. There are stands of spectrographic testing of photoactive materials in a gas media and a set of devices for electrophysical measurements.
