An electron sink is an atom on a molecule or ion that can accept a new bond or lone pair of electrons. Learning to identify the characteristic sources and sinks in different functional groups is the key to learning organic chemistry reaction mechanisms.
A large scanning tunneling microscope, in the labs of the London Centre for Nanotechnology. However, tunneling does require that there is an empty level of the same energy as the electron for the electron to tunnel into on the other side of the barrier. It is because of this restriction that the tunneling current can be related to the density of available or filled states in the sample.
