  Pure SrTiO3 in bulk form is known to be an incipient ferroelectric where the
quantum fluctuations of lattice positions prevent long range ferroelectric
ordering at a finite temperature. We show evidence and identify the origin of
ferroelectric relaxation up to nearly room temperature in single crystalline
SrTiO3. Strikingly, the origin of the observed ferroelectric switching is
intrinsic which is the coherent switching of surface nanopolar regions and not
due to the nucleation and growth of domains, as described by the
Kolmogorov-Avrami-Ishibashi Model.
