COUPLING TERAHERTZ PULSES TO A SCANNING TUNNELING MICROSCOPE

T here has been an ongoing development in the world of microscopy to reach the highest attainable spatial resolution in imaging and capture physical events on the shortest timescales. Carrier scattering and trapping times in nanoparticles, electron thermalization times, and coherent structural dynamics all occur on femtosecond to picosecond timescales. Examples of such physical processes in single nanoparticles require novel ultrafast nanoprobe techniques to explore them .
