Recent studies within the Dynacom framework have shown that low-dimensional materials, composed of atomically thick layered tubes, display new properties. Researchers created structures by wrapping carbon nanotubes in boron nitride nanotubes and used ultrafast optical spectroscopy and time-resolved electron diffraction to monitor electron and atomic motion. They discovered that electrons could transfer between layers, converting their energy into thermal energy rapidly.
In a collaborative work in the Dynacom framework , recent studies have highlighted that materials composed of layered tubes, which are atomically thick and classified as low-dimensional materials, exhibit new properties. Although the static properties of these structures, such as electrical conduction, are well documented, their dynamic properties, including electron transfer between layers and atomic motion triggered by light exposure, have received less attention.
In this study, researchers constructed nested cylindrical structures by wrapping carbon nanotubes in boron nitride nanotubes. They then examined the motion of electrons and atoms induced by ultrashort light pulses on a one-dimensional material. Electron motion was monitored using broadband ultrafast optical spectroscopy, which captures instantaneous changes in molecular and electronic structures due to light irradiation with a precision of ten trillionths of a second FOREST Program .
