A new technical paper titled “Externally-triggerable optical pump-probe scanning tunneling microscopy with a time resolution of tens-picosecond” was published by researchers at University of Tsukuba and UNISOKU Co.
According to the U. of Tsukaba news article, “OPP STM is an essential method for measuring photo-induced charge carrier dynamics in nanostructures, but requires technical advances to meet ultrafast observation needs,” explains Professor Hidemi Shigekawa, senior author. “Our updates to OPP STM enabled study of ultrafast carrier dynamics in a common semiconducting material. Our work will be invaluable in fields such as ultrafast optical communication technologies and photocatalysis,” say the researchers. “Relating the underlying nanostructure of materials to corresponding photo-electrical properties by this user-friendly method will provide fundamental knowledge that’s necessary for improving semiconductor device functionality.”
