Moiré patterns are superlattice structures that appear when two crystals with a lattice mismatch or with a different orientation are superimposed. We have developed a universal classification of all possible periodic Moirés in order to determine their exact crystallographic structure.

Nanowire transistors in the sub10 nm range are subject to process variability. A main cause is the surface roughness of the nanowire. A single dopant centered in the channel can also modify the room temperature electrical characteristics of the transistor.
