Zusammenfassung:	Wick-free vapor chambers and hybrid vapor chambers are described. An example wick-free vapor chamber includes a wettability-patterned condenser configured to control vapor condensation along patterned domains formed on the wettability-patterned condenser; and a wettability-patterned evaporator. The wettability patterned evaporator is configured to: i) accept condensate from the wettability-patterned condenser and ii) transport the condensate along patterned domains formed on the wettability-patterned evaporator to one or more hot domain portions of the wettability-patterned evaporator. An example hybrid vapor chamber includes a wettability patterned condenser configured to control vapor condensation along patterned domains formed on the wettability-patterned condenser; and an evaporator configured to accept condensate from the wettability -patterned condenser.
