Abstract:
1. A thermal imager, comprising: a cross-bar architecture having a plurality of horizontal lines each arranged in a row, a plurality of vertical lines each arranged in a column, and a plurality of cross-points each formed at an intersection between one of the plurality of horizontal lines and one of the plurality of vertical lines; and a plurality of tunnel junction structures each located at one of the plurality of crosspoints, each tunnel junction structure including a first metal layer disposed over one of the plurality of vertical lines, an insulator layer disposed over the first metal layer, and a second metal layer disposed over the insulator layer and underneath one of the plurality of horizontal lines; wherein each tunnel junction structure further includes an inter-layer thermally insulating dielectric layer disposed against each side of the tunnel junction structure extending from the first metal layer up to the second metal layer.
