The authors report an enhancement of the superconducting onset temperature in nanometer-thin YBa2Cu3O7-δ films grown on substrates with nanofaceted surfaces. They theoretically show that the enhancement is mainly driven by electronic nematicity and unidirectional charge density waves, and further suggest that the nanofacets themselves may promote these effects.
