On May 7, 2024, Prof. Lan Xinzheng from Huazhong University of Science and Technology (HUST) was invited to visit the Institute of New Concept Sensors and Molecular Materials and present a report titled “Infrared Colloidal Quantum Dot Materials and Light Detection Technology” in the INCSMM lecture hall. The report was hosted by Prof. Bian Hongtao and attended by Prof. Fang Yu, INCSMM faculty members and graduate students.

Prof. Lan’s main research field is new semiconductor materials and optoelectronic devices, and in recent years, he has carried out systematic and in-depth research on the physical properties regulation of new semiconductors and the preparation of high-performance photovoltaic and optoelectronic detector devices.  Prof. Lan firstly introduced the research progress of colloidal quantum dot infrared detectors, the research work on semiconductor-grade quantum dot materials and high-performance detector devices, which mainly involves the defect passivation of quantum dot materials, the energy level and doping modulation, and the improvement of migration rate, and he also made an outlook on the development of quantum dot infrared detection technology.

After the report, Prof. Lan exchanged views with teachers and students present on related issues and took a group photo with Prof. Fang and Prof. Bian.
