Gigahertz Frame Rate Imaging of Charge-Injection Dynamics in a Molecular Light Source

Light sources on the scale of single molecules can be addressed and characterized their proper sub-nanometer by scanning tunneling microscopy induced luminescence (STML). Such a source driven defined short charge pulses while is detected with sub-nanosecond resolution. We introduce an approach to concurrently image molecular emitter, which based individual defect, its local environment along dynamics at resolution billion frames per second. The observed assigned electron capture occurring in low-nanosecond regime. While emitter's location surface remains fixed, tip modifies energy landscape for injection defect. principle measurement extendable fundamental processes beyond transfer like exciton diffusion.
