What exactly happens inside a crumpled sheet? New simulations, taking into account that the sheet can't pass through itself, reveal that crumpled sheets are more rigid than one might have guessed.
The observation of quantum optical effects in engineered semiconductor structures creates the opportunity to harvest these phenomena in designer devices.
The device properties of polymer semiconductors are heavily dependent on the morphology of the constituent materials. Some of the morphological characteristics of thiophene-based polymers are now being unravelled.
Atomic-scale microscopy of perovskite heterostructures not only provides an understanding of the origin of interface roughness, but also a recipe for improved electronic devices.
