DESIGN AND IMPLEMENTATION OF A COMBINED SCANNING TUNNELING AND NEAR-FIELD OPTICAL MICROSCOPE

The design and the implementation of an integrated form of far-field o ptical, near-field optical and scanning tunneling microscope are prese nted. Gold coated optical fiber points are used as both tunneling and near-field optical probe, allowing a simultaneous recording of scannin g tunneling and near-field optical images of objects. Photon tunneling images are also observed with the same set-up under total internal re flection condition. Finally, we present near-field local spectroscopy using the same system, applied to a high quality Zn0.8Cd0.2Se/ZnSe qua ntum well sample.
