Abstract: The present invention relates to a nanoscale thermoelectric assembly assembled through non-covalent contact between graphene and molecules, and a thermoelectric device comprising same. The present invention ascertains an increase in the Seebeck value due to n-type doping induced by an electron interaction in non-covalent contact of molecules, and confirms the length dependence of the Seebeck value in a graphene-alkylamine SAM system, thereby enabling the development and industrial application of efficient organic thermoelectric devices at a molecular scale.

Abstract: The present invention relates to a thermoelectric measurement system based on a liquid eutectic gallium-indium electrode, whereby thermoelectric performance can be measured with excellent efficiency and high reproducibility even without construction of expensive equipment, various organic molecules as well as large-area molecular layers can be measured, and various thermoelectric materials, such as inorganic materials and inorganic-organic composite materials, can be measured. In addition, non-toxic liquid metal EGaIn is used as an upper electrode, so the damage to even a substance of measurement in the form of a nano-level thin film can be minimized, and the measurement of thermoelectric performance can be performed on even nano- to micro-level organic thermoelectric elements. Therefore, the thermoelectric measurement system is widely utilized across the thermoelectric element industry.
