Abstract

Sample preparation for UHV consists of a series of steps mandatory to be followed in order to get a clean surface. We present here a short recipe from pyrometer calibration to the final step: that of proving that the reconstruction really occurred, namely the 7x7 pattern of the Si(111) surface revealed by LEED and UPS..

Keywords

Si(111)-7×7, XPS, UPS, LEED.
