The study of low dimensional systems is of great interests due to their technical applications as well as the rich fundamental physics. The variety of one dimensional atomic chains can be synthesized on stepped surfaces, which provide opportunities for systematically tailoring the surface properties. The electronic structure of the high vicinal surface plays an essential role to determine the physical properties of the atomic chains as well as the surface catalysis. We have used several surface analysis techniques to study the surface of the (997) single crystal. The scanning tunneling microscopy and low energy electron diffraction results show that the surface has uniform step terrace without any reconstruction. The angle resolved ultra violet photoemission spectroscopy was performed to characterize the band structure of Pt(997) surface by using synchrotron radiation source. Then Fe were carefully deposited on to Pt(997) substrate at room temperature. The atomic resolution STM data shows that Fe atomic chains were formed along the step edges due to the step decoration. Finally angle resolved ultra violet photoemission spectroscopy was also performed to characterize the Fe atomic chains.
