Abstract:
1. A multi-layer device comprising a first substrate and a first patterned electrically conductive layer on a surface of the first substrate, the first patterned electrically conductive layer being transmissive to electromagnetic radiation having a wavelength in the range of infrared to ultraviolet on a surface of the first substrate, the first patterned electrically conductive layer comprising a first material and a second material, the first material being a transparent conductive oxide and the second material having a resistivity that is greater than the resistivity of the first material by a factor of at least 10 2 , the first patterned electrically conductive layer having an average sheet resistance wherein a ratio of the average sheet resistance in a first region of the first electrically conductive layer circumscribed by a first convex polygon to the average sheet resistance in a second region of the first conductive layer circumscribed by a second convex polygon is at least 2, the first and second regions circumscribed by the first and second convex polygons, respectively, each comprising at least 25% of the surface area of the first electrically conductive layer.
