Artifact free time resolved near-field spectroscopy

Time-resolved second harmonic generation near-field scanning optical microscopy.

Novel scanning probe microscopy (SPM) spectroscopic techniques are currently receiving much attention. The increasing number of spectroscopic techniques, when combined with the high spatial resolution that is attainable with SPM, makes it possible to probe a large range of material characteristics on the nanoscopic scale. The ability to probe samples on the nanoscale with femtosecond time resol...

Comparison of Numerical and Experimental Time - Resolved Near - Field Hall

Breathing mode oscillations of a xenon 600 W Hall effect thruster have been studied using temporally resolved experimental data and numerical modeling. Fluctuations in xenon neutral near infrared (810–835 nm) emission in the near field thruster plume have been measured at 1-μs resolution using a high speed, phase-matched intensified charge coupled device. Oscillations in electron temperature, 3...

Time-resolved near-field optics: exciton transport in semiconductor nanostructures.

We present a systematic, temperature-dependent study of excitonic real-space transfer into single GaAs quantum wires using time-resolved low-temperature near-field luminescence spectroscopy. Excitons generated by local short pulse optical excitation in a 250 nm spot undergo diffusive transport over a length of several micrometres and are subsequently trapped into the quantum wire by optical pho...
