Nanoscale photoconductive switching effect applied to atom probe tomography

Abstract : By combining a laser pulse and a high-voltage (HV) pulse on the same sample, field evaporation of materials with poor electrical conductivity using ultra-short HV pulses is reported. Using a pump-probe setup, the shape of HV pulses experienced by surface atoms of the sample apex is experimentally observed. These results are in good agreement with classical models considering the temperature and free carriers produced by a laser pulse giving rise to local photoconduction.
