The emerging in situ high-resolution Synchrotron X-ray Scanning Tunneling Microscopy (SX-STM) technique takes advantage of the chemical, electronic, and magnetic sensitivity of synchrotron radiation and combines it with the sub-nanometer spatial resolution of scanning tunneling microscopy. | ||
Generally, an insertion device of a synchrotron storage ring produces high brilliant x-rays. The photon energy is then selected by a monochromator before x-rays arrive on the sample. The microscope is located on a damping stage that offers vibration isolation. It can be coarse aligned (x,y,z,θ) in respect to the x-ray beam. A sharp tip is scanned over the sample surface utilizing a piezo scanner. The tip current provides chemical contrast, when a special topography filter is used. | ||
