1. A rectifier for converting an oscillating electromagnetic field into a direct current comprising:

  • (a) an electrically conductive antenna layer configured to absorb at least 1% of at least one selected wavelength of electromagnetic radiation;

    (b) an electrically conductive mirror layer, configured to provide an electromagnetic mirror charge of the antenna layer;

    (c) an electrically insulating barrier layer, positioned between the antenna layer and the mirror layer and having a thickness of about 0.3 nm to about 20 nm; and

    (d) an electronic circuit electrically connected between the conductive mirror layer and the conductive antenna layer,wherein the rectifier is configured to enable electron tunneling through the electrically insulating barrier layer and wherein the antenna layer and the mirror layer are selected to provide tunneling matrix elements that result in a responsivity factor greater than about 10 V

    1
    for at least one voltage within the range from about −

    100 mV to about 100 mV.
