Studies of thermopower in molecular junctions permit access to the atomic-detailed energy topography across junctions and how thermopower is associated with chemical structure of the active molecular components inside junctions. This presentation describes a liquid metal-based thermoelectric junction technique and structure-thermopower relationships established with the technique. Cone-shaped liquid Ga-In alloy (EGaIn) microelectrode allows us to achieve high yields of working junctions and thus statistically sufficient thermoelectric data sets. We estimated thermopowers of EGaIn and the Ga2O3 layer on the EGaIn conical tip and successfully validated our platform with widely studied molecules, oligophenylene thiolates.
