Abstract:
The sepn. of UPS and metastable impact electron spectroscopy (MIES) is usually performed by a time-of-flight (ToF) sepn. using pre-set ToF for both types of signal. The authors present a new, improved ex situ signal sepn. method for the sepn. of MIES and UPS for every single measurement. Signal sepn. issues due to changes of system parameters can be overcome by changing the ToF sepn. and therefore allowing for the application of a wider range of measuring conditions. The method also enables to i...     »
