New Preprint: Deterministic Formation of Single Organic Color Centers in Carbon Nanotubes
We are excited to announce the release of our latest research paper on arXiv titled “Deterministic Formation of Single Organic Color Centers in Single-Walled Carbon Nanotubes”. This work presents a significant advancement in the field of quantum light sources using carbon nanotubes. Research Highlights In this work, we demonstrate: A novel technique for deterministic creation of single organic color centers in carbon nanotubes using in-situ photochemical reaction Precise control over individual color center formation through monitoring of discrete photoluminescence intensity changes Position-controlled formation of color centers, validated through photoluminescence imaging Confirmation of quantum nature through photon antibunching measurements This technique represents a crucial step forward in engineering atomically defined quantum emitters in carbon nanotubes, paving the way for their integration into advanced quantum photonic devices and systems.

Feng's paper published in ACS Applied Materials & Interfaces - Optimizing WS2 Growth with Bayesian Optimization
Bayesian Optimization for Controlled Chemical Vapor Deposition Growth of WS2 © 2024 American Chemical Society Accelerating 2D Material Synthesis with Machine Learning Published in ACS Applied Materials & Interfaces, 2024 Our latest research employs Bayesian optimization (BO), a machine learning technique, to optimize the growth of monolayer WS2 through chemical vapor deposition (CVD). By maximizing photoluminescence (PL) intensity, we achieved an impressive 86.6% increase in only 13 rounds of optimization. This work demonstrates the potential of BO to surpass traditional methods like random search, offering faster convergence to optimal growth conditions.
