What Soviet-born Dutch-British physicist wrote a paper that described devices that contained just one, two, or three atomic layers?
Bilayer graphene Bilayer graphene is a material consisting of two layers of graphene. One of the first reports of bilayer graphene was in the seminal 2004 "Science" paper by Geim and colleagues, in which they described devices "which contained just one, two, or three atomic layers"
Neutron depth profiling Neutron depth profiling (NDP) is a near-surface analysis technique that is commonly used to obtain profiles of concentration as a function of depth for certain technologically important light elements in nearly any substrate. The technique was first proposed by Ziegler "et al." to determine the concentration profiles of boron impurities in silicon substrates, and later improved by Biersack and coworkers to much of its existing capabilities.
