Periodic Reporting for period 3 - UpTEMPO (Ultrafast tunneling microscopy by optical field control of quantum currents)
Période du rapport: 2022-09-01 au 2024-02-29
This goal will be achieve by generating light pulses that consist in a single cycle of the electromagnetic oscillation. These transients can be focused on an STM tip to act as the source of the bias that drives the current through the sample under investigation with atomic resolution. The ultrafast STM can then be used in combination with other ultrashort pulses employed to excite the samples to probe and derive movies of the charge motions in molecules and nanostructures. The final goal is to better understand and harness fundamental processes like charge localization and germination with applications that range from sensing to photovoltaics.
