Sungkyunkwan University team finds synthesis mechanism of semiconductor nanocrystals

“A Sungkyunkwan University research team has identified the synthesis mechanism of next-generation infrared semiconductor nanocrystals, key materials for autonomous driving and smart sensors, the university said Thursday. The mechanism was first discovered by a team led by Jeong So-hee, associate professor at the university’s department of energy, opening a new paradigm for semiconductor material design. The findings illuminate the process of synthesizing infrared semiconductors known as III-V nanocrystals, which are extremely small semiconductor crystals made from elements in Groups III and V of the periodic table. The university said the study tracked the reduction mechanism of heavy pnictogen elements, a process that had long been a mystery, adding that it is expected to accelerate the commercialization of high-performance infrared optoelectronic devices. A pnictogen refers to any chemical element in the nitrogen group, including nitrogen, phosphorus, arsenic and bismuth. The findings are drawing attention due to the growing importance of applying infrared-based technologies to areas
