We recently enjoyed a spring outing at Dianshan Lake with our group. Alongside appreciating the beauty of the lakeshore, we were entertained with some ukulele music and participated in a delightful BBQ. The event also included a fun card-playing session. Everyone had a wonderful time, cherishing the joyous moments together.

Prof. Peng was invited to present our research to the undergraduate students at Zhiyuan College. The presentation was met with enthusiastic participation, with numerous students actively engaging in the discussion and demonstrating a keen interest in our work.

After multiple design revisions and four months of construction, the renovation of our laboratory is nearly complete. Notably, we eliminated water hazards, significantly reducing electromagnetic and mechanical noise, and constructed an ultraclean room specifically for the assembly of an ultrafast terahertz scanning tunneling microscope (THz-STM). We extend our gratitude to all team members for their dedicated efforts!

Welcome! Zeyuan graduated from Fuzhou University in 2021. Initially, he studied condensed matter theory for one year but then chose to immerse himself in the world of Scanning Probe Microscopy (SPM). Now, he is driven by a strong ambition to develop novel SPM techniques and utilize them to explore the fascinating microscopic world.

Scanning probe microscope (SPM), which includes scanning tunneling microscope (STM) and atomic force microscope (AFM), can obtain the morphology and rich physical properties of surfaces at atomic and molecular scales via raster-scanning the sample with a sharp tip. Since its invention, SPM has led to a paradigm shift in the understanding and perception of matter. In recent years, the emergence of qPlus-type force sensors with high-quality factor has pushed the resolution and sensitivity of SPM to a new level, providing unprecedented opportunities for the precise detection and manipulation of chemical structures, charge states, electronic states, and spin states. Here we will first briefly describe the historical development and basic working principles of AFM, then focus on the advantages of qPlus-AFM and its representative applications in single atoms, single molecules and low-dimensional materials. Finally, we give an overview of its future development trends and potential applications.(link)
