Abstract

Atomically thin metallic chains serve as pivotal systems for studying quantum transport, with their conductance strongly linked to the orbital picture. We report an unusual electromechanical response in Au/ferrocene/Au junctions, manifested as tilted “Z”- and “V”-shaped features with more than an order-of-magnitude conductance change upon stretching at cryogenic temperatures, a striking deviation ...
