Caption

The picture shows a layer of phase-transition material SmNiO3 placed on top of a Columbia Engineering School logo. The transparency of the material can be controlled by electron doping under ambient conditions. Pristine SmNiO3 is opaque; partial phase-transition makes the material translucent, and complete phase-transition makes it transparent.
