Most surface spectroscopic techniques involve probing the surface by exposing it to a flux of "particles" (hν, e-, A+ ....) and simultaneously monitoring the response to this stimulation by, for example, measuring the energy distribution of emitted electrons. In their most basic form, these techniques collect information from a relatively large area of surface (∼ mm2 ). In most cases, however, there are variations of these techniques which permit either,
- The requirement in both cases is for spatial localisation of the spectroscopic technique. This may be achieved in one of two ways,
