ARPES/STM study of the surface terminations and 5f-electron character in URu_2Si_2

Hidden order in URu_2Si_2 has remained a mystery now entering its 4th decade. The importance of resolving the nature of the hidden order has stimulated extensive research. Here we present a detailed characterization of different surface terminations in URu_2Si_2 by angle-resolved photoemission spectroscopy, in conjunction with scanning tunneling spectroscopy and...
