Light-modulated scanning tunneling spectroscopy (LM-STS), a potential method that provides us with the technique to investigate spatially resolved carrier dynamics such as surface photovoltage is discussed. With the results obtained for a GaAs(110) p-n junction as an example, the basic principle and experimental techniques of LM-STM are introduced.
