Nanoscale dynamics probed by laser-combined scanning tunneling microscopy

With the miniaturization of functional devices, the difference in the electronic properties, for example, due to the structural nonuniformity in each element of nanoscale blocks has an ever more crucial influence on macroscopic functions. Laser-combined scanning tunneling microscopy, a potential method that enables us to probe the photoinduced carrier dynamics on the nanoscale, is reviewed with the latest results.
