Caption: Above: A single molecule (blue) is held between a pair of gold electrodes (yellow) which are moved to left and right, stretching the molecule’s length. Below: As the molecule is stretched, the Highest Occupied Molecular Orbitals (EHOMO) shift toward the Fermi level (EF) of the electrodes—region of maximum electrical conductance. The effect of the geometric change in the molecule as it is stretched is to lower the energy barrier required for electron transport.
