Rb2Ti2O5 (RTO) has recently been demonstrated to be a solid electrolyte, producing colossal capacitance when interfaced with metals. In order to understand the mechanisms leading to such colossal equivalent permittivity (up to four orders of magnitud

Recent results have demonstrated an exceptionally high permittivity in the range 200–330 K in crystalline titanium oxide Rb2Ti2O5. In this article, the possibility of a structural transition giving rise to ferroelectricity is carefully inspected. I

A colossal dielectric constant is demonstrated (up to 109) in the lamellar perovskite titanate Rb${}_{2}$Ti${}_{2}$O${}_{5}$ at room temperature. Due to a combination of high purely internal ionic conduction and immaterial electronic conduction, this
