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"
Johannes Rydberg Johannes (Janne) Robert Rydberg (8 November 1854 – 28 December 1919) was a Swedish physicist mainly known for devising the Rydberg formula, in 1888, which is used to predict the wavelengths of photons (of light and other electromagnetic radiation) emitted by changes in the energy level of an electron in a hydrogen atom.
