Abstract: 
A truly bulk-terminated SrTiO3(001) surface prepared by cleaving in situ was investigated with angle-resolved photoemission spectroscopy (ARPES) and noncontact atomic force microscopy (ncAFM). The (1×1) SrTiO3(001) surfaces were achieved through our cleaving procedure that exploits the strain-induced ferroelectric transition in SrTiO3, and provides both possible surface terminations, TiO2 and SrO. Each hosts a specific two-dimensional electron liquid (2DEL): the first with split and the other with degenerate bands. The origin of the 2DELs and the band-splitting mechanisms are elucidated by correlating the observed reciprocal- and real-space electronic and atomic structure.
