ABSTRACT:
A device for controlling the flow of electric current is provided. The device comprises a first conductor as thin film form; a second conductor switchably coupled to the first conductor to alternate between an electrically connected state with the first conductor and an electrically disconnected state with the first conductor. At least one conductor further comprises an electrical contact, the electrical contact comprising a solid matrix comprising a plurality of pores; and a filler material disposed within at least a portion of the plurality of pores. The filler material has a melting point of less than about 575 K. A method to make an electrical contact is provided. The method includes the steps of: providing a substrate; providing a plurality of pores on the substrate; and disposing a filler material within at least a portion of the plurality of pores. The filler material has a melting point of less than about 575 K.
