abstract = {Perovskite SrIrO3 (SIO) films epitaxially deposited with a
thickness of about 60 nm on various substratematerials
display a nearly strain-relieved state. Films grown on
orthorhombic (110) DyScO3 (DSO) are found todisplay an
untwinned bulklike orthorhombic structure. However, film
deposition on cubic (001) SrTiO3 (STO)induces a twinned
growth of SIO. Resistance measurements on the SIO films
reveal only weak temperaturedependence, where the resistance
R increases with decreasing temperature T. Hall measurements
show dominantelectronlike transport throughout the
temperature range from 2 to 300 K. At 2 K, the electron
concentration andresistivity for SIO on STO amounts to ne =
1.4 × 1020 cm−3 and 1 m cm. Interestingly, the film
resistance ofuntwinned SIO on DSO along the [1-10] and the
[001] direction differs by up to $25\%,$ indicating
pronouncedanisotropic electronic transport. The anisotropy
of the resistance increases with decreasing T and displays
adistinct maximum at around 86 K. The specific T dependence
is similar to that of the structural anisotropy√(a2 + b2
)/c of bulk SIO. Therefore, anisotropic electronic transport
in SIO is very likely induced by theorthorhombic distortion.
Consequently, for twinned SIO films on STO anisotropy
vanishes nearly completely.The experimental results show
that structural changes are very likely responsible for the
observed anisotropicelectronic transport. The strong
sensitivity of the electronic transport in SIO films may be
explained in terms ofthe narrow electronlike bands in SIO
caused by spin-orbit coupling and orthorhombic distortion.},
