We demonstrate unequivocal signatures of room-temperature quantum interference (QI) in vertical tunneling transistors, formed from self-assembled monolayers (SAMs), with stable room-temperature switching operations.
As a result of constructive QI effects, the conductances of the junctions formed from anthanthrene-based molecules with two different connectivities differ by a factor of 34, which can further increase to 173 by controlling the molecule-electrode interface with different terminal groups.

This work was conducted by Dr. Shi-Xia Liu in collaboration with UCLA (USA), Lancaster University (UK), and Hunan University (China).
