Nanostructures are a new level of understanding. With the specific characteristic of nanostructures, a variety of high-performance nano-devices can be developed. The design and construction of nanostructures to further reveal and regulate the physical properties of nanostructures is one important pathway to achieve this goal. Based on this, we first study the central issue that builds nano-structure with surface/interface photoelectric properties. With the goal of developing new high-performance optoelectronic nano-devices, we have conducted systematic research work on the construction of nanostructures, the characterization and regulation of optoelectronic properties on surface interfaces and optoelectronic nanodevices. The main content includes:

1. Nanostructure construction and processing
