Angle-Resolved PhotoEmission Spectroscopy (ARPES)

The MPI CPfS end station in NSRRC is capable of performing photoemission spectroscopy (PES), angle-resolved photoemission spectroscopy (ARPES), and X-ray absorption spectroscopy (XAS) experiments. The spectrometer mainly consists of a MBS hemispherical analyzer with a 2D-CCD detector. The MBS spectrometer has a mean radius of 200 mm with 9 changeable slit sets (aperture and object slits). The energy resolution of the analyzer is better than 1 meV. The angular resolution is smaller than 0.1o. The MBS 2D-CCD detector has a wide-angle span of ±20o, which covers the first Brillouin Zone of most of interesting oxides. A five-axis (X,Y,Z,Q,Y) manipulator is equipped and the sample stage can be cooled down to 10 K.

A versatile in-vacuum transferring and sample preparation system  is equipped. The main piece is a PREVAC transferring system. Satellite chambers are equipped with a LEED, an ion sputtering gun, and e-beam heaters for surface science characterization and preparation. A molecular-beam-epitaxy (MBE) film growth facility can also be docked onto the PREVAC transferring system for in-vacuo thin film projects.
