Research

Our research group is dedicated to exploring the frontiers of quantum nanostructures and advancing our fundamental understanding of their properties. We focus on creating atomically precise quantum defects in nanoscale materials such as single-walled carbon nanotubes and atomically thin layers. By leveraging micro/nano processing technology, we fabricate electronic devices on these quantum nanostructures for precise electronic control. Through advanced microscopic spectroscopic measurements, we investigate the physical properties of these materials in detail, enabling us to manipulate quantum effects and develop novel quantum devices.

Quantum defects

Our research in quantum defects focuses on creating and characterizing precisely defined quantum emitters in nanomaterials. We explore both single-walled carbon nanotubes and atomically thin layers, with particular emphasis on organic color centers and quantum emitters in hexagonal boron nitride.

• Formation of organic color centers in pristine carbon nanotubes
• Quantum emitters in hexagonal boron nitride

Optothermal engineering

We investigate resonant exciton-phonon coupling in carbon nanotubes, which enables selective excitation of bright excitons and holds promise for laser cooling applications.

• Upconversion photoluminescence in carbon nanotubes

2D optoelectronics

Our work in 2D optoelectronics combines advanced micro/nano processing with quantum nanostructures to create devices with precisely controlled electronic properties. We focus on understanding carrier dynamics, energy transfer mechanisms, and device stability in various 2D materials.

• Photocarrier relaxation pathway in two-dimensional semiconductors
• Efficient energy transfer in ultra-thin materials
• Photodetection in electrolyte-gated transistors of two-dimensional crystals
• Bilayer phosphorene stability under MoS2 passivation
