The understanding of the origin of the intrinsic stress during the formation of polycrystalline thin films and coatings is a topic with deep technological implications, because residual intrinsic stress endures after the film is incorporated into a device. The accumulation of this stress under operating conditions causes the thermomechanical fatigue that is estimated to be responsible for 90% of mechanical failures in current devices.

Microwave stimulated superconductivity is apparently a counter intuitive phenomenon, its significance being dependent on vortex mobility and proximity to the critical temperature.
