Appeal No. 2006-1545 Application 10/254,326 heterojunction PN diode formed from two semiconductor materials having different band gap energy levels, which increases the forward-to-reverse current ratio. Claim 42 is reproduced below. 42. A semiconductor structure comprising: a first conductor and a second conductor; a steering element in circuit communication with the first conductor and comprising at least first and second semiconductor materials, the first semiconductor material having a first band gap energy level, the second semiconductor in electrical communication with the first semiconductor and having a second band gap energy level, wherein the second band gap energy level is different from the first band gap energy level; and a state change element in circuit communication with the steering element and the second conductor and comprising a selectable high impedance state and a selectable low impedance state. - 2 -Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
