Scientists successfully visualized the ultrafast dynamics of quasi-particles known as excitons, which are generated in carbon nanotubes upon light excitation. This was achieved with spatial and ...

Excitons--bound pairs of electrons and holes created by light--are key to the optoelectronic behavior of carbon nanotubes (CNTs). However, because excitons are confined to extremely small regions and ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
