Surface structural analysis of SrF2(111) using low-energy atom scattering spectroscopy

“…The peak signal from Sr atoms can be seen, but the peak of F atom signals has a broad distribution because of multiple scattering due to the 4 He°incident beam. The peak signal from 12 C that typically appears at 4. 38 μs were not seen in Fig.…”

“…Details of LEAS apparatus are available in a previous paper. 12) Herein, we will briefly describe the equipment. First, low-energy ion beams were produced and chopped by a pulse signal (100 kHz, +70 V) using a electrostatic deflector.…”

“…Therefore, we developed a low-energy atom scattering (LEAS) spectroscopy system for analyzing such insulator surfaces. [10][11][12][13][14] A low-energy atom beam is produced by passing an ion beam through a gas of the same type as the ion beam. 15,16) The surface structure can be directly determined in a real space by analyzing the angular anisotropy of atom scattering intensities.…”
