Abstract

Read online

Energy alignment in molecular tunnelling junctions is desirable for altering their electrical properties, however controllability is still an issue. Here the authors report a 2 orders-of-magnitude increase in the tunnelling current via chemical control of the energy-level alignment at a two-terminal junction.
