Claim Text:
1. A non-ohmic select device, comprising: at least two tunnel barrier regions formed between a first metal material and a second metal material; a third metal material formed between a first tunnel barrier region and a second tunnel barrier region of the at least two tunnel barrier regions; and a fourth metal material formed between the second tunnel barrier region and a third tunnel barrier region; wherein the non-ohmic select device is a two terminal select device that supports bi-directional current flow therethrough; wherein the first tunnel barrier region comprises a first semiconductor material formed in direct contact with the first metal material and the third metal material; wherein the second tunnel barrier region comprises a second semiconductor material formed in direct contact with the second metal material and the fourth metal material; and wherein the third tunnel barrier region comprises a third semiconductor material formed in direct contact with the third metal material and the fourth metal material such that Schottky barrier junctions are formed at interfaces between the first tunnel barrier region and the first metal material, between the first tunnel barrier region and the third metal material, between the second tunnel barrier region and the fourth metal material, between the second tunnel barrier region and the second metal material, between the third tunnel barrier region and the third metal material, and between the third tunnel barrier region and the fourth metal material; and wherein at least one of the first and the second semiconductor materials comprises at least one semiconductor material selected from the group consisting of:
