Abstract

Layered Compounds Interaction of electron donor and acceptor molecules with graphene and carbon nanotubes brings about major changes in the electronic structure and properties of these nanocarbons. In their Communication on page 1780 ff. (highlighted on the Inside Cover), C. N. R. Rao et al. report that an electron donor such as tetrathiafulvalene (TTF) transfers an electron to graphene-like few-layer MoS2, thus resulting in the formation of the TTF radical cation (TTF+.). This interaction with TTF significantly changes the band gap of MoS2. By contrast, the electron acceptor tetracyanoethylene does not interact with MoS2 as it is a p-type material.
