Synthesis and investigation of advanced materials based on low-dimensional systems by fast XPS — •Sergey Babenkov¹, Olga Molodtsova¹, Victor Aristov^1,2, Frank Scholz¹, Joern Seltmann¹, Ivan Shevchuk¹, Leif Glaser¹, and Jens Viefhaus¹ — ¹DESY, Hamburg, Germany — ²ISSP RAS, Chernogolovka, Russia

Generally the synthesis and consequently many properties of advanced materials involve fast reaction processes, which should be precisely controlled and characterized. We propose fast electron spectroscopy for this task. The end-station for such investigations was designed, built up and installed into the soft X-ray beamline P04 at PETRA III (DESY Hamburg). The system is based on a hemispherical electron spectrometer ARGUS (Omicron NanoTechnology) with parallel detection, which in combination with the high brilliance of PETRA III at XUV beamline P04 provides the possibility of taking extremely fast (below 1 sec/spectrum) soft x-ray photoelectron spectra of high quality.

Using such unique set-up first of all we have studied the process of graphene formation by control the time/temperature/rare-gas pressure parameters. In addition we present metal-organic interface formation by in-situ indium deposition onto thin organic molecular crystal (CuPcF4) at room temperature conditions.
