Population of metal oxide nanosheets, preparation method thereof, and electrical conductor and electronic device including the same

An electronic device comprising:

• a substrate having a first surface and a second surface opposite to the first surface;
• a first conductive layer having a third surface and a fourth surface opposite to the third surface and comprising a plurality of layered metal oxide nanosheets, the first conductive layer being disposed on the substrate so that the third surface of the first conductive layer faces the first surface of the substrate;
• and
• a second conductive layer disposed on the substrate and comprising an electrically conductive metal nanowire,
• wherein adjacent metal oxide nanosheets of the plurality of metal oxide nanosheets contact to provide an electrically conductive path between the contacting metal oxide nanosheets,
• wherein the metal oxide nanosheets of the plurality of metal oxide nanosheets comprise an oxide of Re, Os, Ru, Ta, Ir, W, Ga, Mo, In, Cr, Rh, Mn, Co, Fe, or a combination thereof, and
• wherein the plurality of metal oxide nanosheets have an average lateral dimension of greater than or equal to about 1.1 micrometers, and
• wherein the first conductive layer has a sheet resistance of less than or equal to about 33000 ohms per square.
