Research Abstract |
We developed a scattering-type scanning near-field optical microscope, which does not use any external light source. With the developed microscope, we performed passive near-field microscopy of spontaneous thermal emission. By scanning a near-field probe on a GaAs/Au sample at room temperature without an external light, we obtained near-field components derived from thermally activated surface plasmon on Au. The spatial resolution of 150nm (1/100 of wavelength) was successfully achieved.
