ABSTRACT:
A scanning tunneling microscope includes a probe, an optical waveguide, a photodetector, a bias power supply. The probe includes a tip made of a sharpened light transparent material and arranged to be opposite and perpendicular to a sample incorporating a quantum structure, and a light transparent electrode which covers a surface of the tip and is optically transparent. The optical waveguide has one end arranged on a proximal side of the tip. The photodector is arranged on the other end of the optical waveguide to detect luminescence from the sample. The bias power supply applies a bias voltage between the light transparent electrode and the sample.
