Molybdenum Correlated Metal Compounds for Transparent Conductive Oxides

The patent changes the fundamental material parameter from wide band gap semiconductor to correlated metal, which inherently provides high carrier density without requiring heavy doping. This parameter change shifts the plasma frequency out of the visible region through interelectron repulsion, simultaneously achieving high electrical conductivity and high optical transmission in the visible spectrum

The patent creates composite transparent conductive materials by combining metal elements with specific oxidation states (such as Mo4+) and dopants (such as alkali metals like K, Rb, Cs) to form correlated metal compounds. This composite approach enables the material to exhibit both high carrier density from the metal and enhanced optical transmission from the correlated electron effects

The patent changes the electronic structure parameter of the metal by introducing correlated electron effects through specific oxidation states and doping. This changes the plasma frequency from the visible region to other spectral regions, allowing the metal to maintain high conductivity while becoming transparent in the visible spectrum

The patent introduces dopant elements (such as alkali metals) as intermediaries that modify the electronic structure of the metal. These dopants create correlated electron states that shift the plasma frequency, acting as a mediator between the high carrier density requirement and the optical transmission requirement
