Scanning tunneling microscopy (STM) and angle-resolved photoemission spectroscopy (ARPES) were used to study the atomic and electronic structures of the Si(111)-$\sqrt{21}\times\sqrt{21}$-(Ag+Cs) surface ($\sqrt{21}$-Cs in short), which was induced by depositing caesium atoms on the Si(111)-$\sqrt{3}\times\sqrt{3}$-Ag surface at room temperature (RT). Compared with previously reported STM images of noble-metal induced $\sqrt{21}\times\sqrt{21}$ phases including the Si(111)-$\sqrt{21}\times\sqrt{21}$-(Ag+Ag) and Si(111)-$\sqrt{21}\times\sqrt{21}$-(Ag+Au) surfaces ($\sqrt{21}$-Ag and $\sqrt{21}$-Au, respectively), the $\sqrt{21}$-Cs surface displayed quite different features in STM images. The ARPES data of the $\sqrt{21}$-Cs surface revealed an intrinsic dispersive surface-state band, together with a non-dispersive one near the Fermi level, which was also different from those of the $\sqrt{21}$-Ag and $\sqrt{21}$-Au surfaces. These results strongly suggest different atomic arrangements between Cs- and noble-metal induced $\sqrt{21}\times\sqrt{21}$ phases. Unlike the $\sqrt{21}$-Ag and $\sqrt{21}$-Au phases, the framework of the initial Si(111)-$\sqrt{3}\times\sqrt{3}$-Ag substrate is totally broken at the $\sqrt{21}$-Cs phase.
