Avoiding photothermal noise in laser assisted scanning tunneling microscopy

Thermal expansion produced by laser irradiation of the tunneling junction is analyzed, as a necessary step towards detection and identification of other laser induced currents in scanning tunneling microscopy (STM). Solving a tridimensional heat diffusion model, the amplitude of thermal expansion as...
