Abstract:
An apparatus for making an array of materials by electrochemical deposition and for screening members of the array of materials for an electrical property, the apparatus comprising:a substrate having spatially addressable working electrodes corresponding to the members of the array of materials; at least one other electrode, the at least one other electrode and the spatially addressable working electrodes adapted to apply an independently variable electrical potential between the spatially addressable working electrodes and the at least one other electrode so that when the substrate and the at least one other electrode contact a solution containing ions, ions in said solution undergo chemical reaction at the spatially addressable working electrodes forming the array of materials, wherein at least two members of the array of materials have different compositions; a detector for measuring the electrical property of the members of the array of materials, with the spatially addressable working electrodes electrically connected to the detector; and reference electrodes having ends located adjacent ends of the spatially addressable electrodes; wherein the spatially addressable working electrodes, the at least one other electrode and the reference electrodes are adapted to apply the independently variable electrical potential between each of the spatially addressable working electrodes and the at least one other electrode.
