Abstract
The invention relates to a new type of material and describes a novel material and way to improve the transparency of a transition metal oxide by employing an anionic doping strategy to modify the transparency. At the same time a cationic dopant is used to improve conductivity.
Claims16
A transparent conducting oxide material comprising:
- a host oxide in form X2O3, preferably of a corundum type, wherein X is selected from at least one of Vanadium, Chromium, Aluminium or Iron;
- a first doping element, wherein said first doping element is selected from at least one of Magnesium, Zinc, Lithium, Copper, Chromium, Iron, Vanadium, Aluminium or Calcium;
- and
