We analytically identify sufficient conditions for manifesting thermal rectification in two-terminal hybrid structures within the quantum master equation formalism. We recognize two classes of rectifiers. In type A rectifiers the contacts are dissimilar. In type B rectifiers the contacts are equivalent, but the system and baths have different particle statistics, and the system is (parametrically) asymmetrically coupled to the baths. Our study applies to various hybrid junctions including metals, dielectrics, and spins.
