Abstract
A rectenna is used for full-wave rectification of infrared radiation to produce electricity. In the rectenna, a metallic grating overlies a semiconductor body. A tunnel barrier is interposed between each grating element and the semiconductor body. Each of the grating elements overlies a bridge pair consisting of a region of n-doped semiconductor and a region of p-doped semiconductor, both of which are embedded in more lightly doped host semiconductor material. Each of the two regions that compose the bridge pair forms a rectifying tunnel junction through a tunnel barrier to at least one overlying grating element. Each of the two regions also forms a semiconductor junction with the host semiconductor material.
