abstract = {The metal-insulator transition temperature of SrTiO3 films
grown on single crystalline DyScO3 (110), TbScO3 (110), and
GdScO3 (110) substrates is tuned by the lattice-mismatch
epitaxial strain. X-ray diffraction measurements demonstrate
that all films are grown epitaxially. A systematic variation
in the electrical transport properties has been observed
with the change in the lattice mismatch between films and
various substrates. It is shown that by a proper selection
of mismatch between 0 to 1.6 $\%$ range of this study) and
thickness between 5 to 200 nm of films, it is possible to
control and precisely tune the metal-insulator transition
temperature to a desired value, i.e. from 10 to 300 K. We
demonstrate electrically switchable resistance using planar
electrodes with 200-1000 nm distance. The electronic
transport experimental results show an anisotropy transport
for the anisotropically strained films. This confirms that
the anisotropic misfit induced two in-plane phases have
different behaviors that is highly directionally-dependent.
Our results might be of importance for applications in
storage, memory, and even artificial synaptic devices for
neuromorphic computing.},
