Professor Ching-Ray Chang of our department has had his research published in the prestigious international journal Nature Communications.
As a distinguished professor in the Department of Physics at Chung Yuan Christian University, Professor Chang joined the research team led by Professor Han-Chun Wu of the School of Physics at Beijing Institute of Technology, collaborating with Professor Guan-Ming Hong of National Kaohsiung University of Science and Technology and Professor Igor V. Shvets of Trinity College Dublin. Together, they developed a novel miniature spectrometer based on a SnS2/ReSe2 van der Waals heterostructure. This spectrometer offers functionalities including photodetection, spectral reconstruction, spectral imaging, long-term image memory, and signal processing. Despite its incredibly small size of only 19 micrometers, the spectrometer boasts a high spectral resolution of 5 nm and a long-term image memory of up to 104 seconds. The related findings were published in Nature Communications under the title “A Miniature Spectrometer with Intrinsic Long-Term Image Memory”. Professor Chang currently serves as the director of the Chung Yuan Quantum Information Center and as a consulting advisor at Foxconn Research Institute.
