The design and fabrication of materials that simultaneously contain more than one type of functional components, so-called multi-functional materials, is highly desirable for a range of technological applications. Among a variety of possible building blocks, inorganic nanocrystals (NCs) have proven to be ideal ones and can be used as â€˜artificial atomsâ€™ to generate higher-order architectures, especially in an ordered and controllable manner, which is also called NC superlattices.
In Chen's lab, we are generating NC superlattices from the NCs with different sizes or natures (e.g., semiconductor, metallic, or magnetic) or both. By using chemical and physical tools, we are trying to explore and understand the novel and enhanced collective properties from the near-field coupling that occurs between NC neighbors inside the superlattices.
