Adsorption Experiment - Experimental Setup

The adsorption experiments are performed in an ultrahigh vacuum (UHV) chamber operating at a working pressure below 5×10-11 mbar. Surface conditions are checked by low-energy electron diffraction (LEED) and Auger electron spectroscopy (AES). Hydrogen is supplied by a high flux molecular beam apparatus with a nozzle - sample distance of about 30 cm. Sticking coefficients down to 1×10-8 can be measured. For SHG, the pump radiation with a wavelength of 1064 nm and a pulse duration of 10 ns is provided by a Q-switched Nd:YAG laser operating at repetition rates between 10 and 30 Hz. The fluence on the sample varied between 30 and 100 mJ/cm2, depending on sample temperature.
