Spectroscopy of Light Emission from a Scanning Tunneling Microscope in Air
نویسندگان
چکیده
Light emission has been detected at the tip-sample junction of a Scanning Tunneling Microscope (S.T.M.) in air on noble metallic surfaces. A spectroscopic study of emitted photons for Au-Au and Ptlr-Au tunneling junctions is presented. The general aspect of the spectra depends on the materials used in the junctions; a study of the spectra as a function of tunneling current and surface bias voltage reveals similar and reproducible characteristics.

Time-resolved scanning tunneling microscope light emission spectroscopy of Sb2Te3
We have successfully added ps temporal resolution to scanning tunneling microscope (STM) light emission spectroscopy. STM light emission spectra of Sb2Te3 were measured in the configuration that the tip sample gap of the STM is irradiated by a pair of pump and probe laser pulses with a duration less than 2 ps each, and were analyzed as a function of optical delay time between the pump and probe...
متن کاملFiber optic light collection system for scanning-tunneling-microscope-induced light emission.
We report a compact light collection scheme suitable for retrofitting a scanning tunneling microscope (STM) for STM-induced light emission experiments. The approach uses a pair of optical fibers with large core diameters and high numerical apertures to maximize light collection efficiency and to moderate the mechanical precision required for alignment. Bench tests indicate that efficiency reduc...

Imaging of surface plasmon polariton interference using phase-sensitive photon scanning tunneling microscope
We report the surface plasmon polariton interference, generated via a ‘buried’ gold grating, and imaged using a phase-sensitive Photon Scanning Tunneling Microscope (PSTM). The phase-resolved PSTM measurement unravels the complex surface plasmon polariton interference fields at the gold-air interface.
متن کاملInfrared spectroscopy of molecular submonolayers on surfaces by infrared scanning tunneling microscopy: tetramantane on Au111.
We have developed a new scanning-tunneling-microscopy-based spectroscopy technique to characterize infrared (IR) absorption of submonolayers of molecules on conducting crystals. The technique employs a scanning tunneling microscope as a precise detector to measure the expansion of a molecule-decorated crystal that is irradiated by IR light from a tunable laser source. Using this technique, we o...
