Thin mica shows semiconducting behavior, say scientists in new study: Mica, a well-known insulator, has been found to behave as a semiconductor when thinned down to a few molecular layers

In 2004, researchers from the University of Manchester used adhesive tape to pull sheets of single carbon atoms away from graphite to make graphene — a material that is 1000 times thinner than human hair yet stronger than steel. This ground-breaking exfoliation technique paved the way for the development of a wide range of two-dimensional…
