In terms of Smartphone, Tablet and TV displays is nothing without the indium tin oxide material. Now 60 years indium tin oxide is used in 90 percent of all displays and is partly responsible for the high prices in the electronics sector due to its high price. Recently, a new material has been discovered but that has the same properties such as indium tin oxide, is however cheaper.
The costs for the production of displays have risen continuously in recent decades differently than the production of chips and storage devices. Indium tin oxide has proved as the best material for the production of displays. It is easy to work with, malleable, has excellent electrical conductivity and good optical properties. Unfortunately, but also its price has grown massively in the last 10 years. This is because among other things, that the material was so far without any alternative. This circumstance may be changing now. A team of scientists around to Roman Angel-Herbert from the Pennsylvania State University has discovered a material that soon indium tin oxide instead of in display production use could find.
The team’s goal was to find an alternative material to indium tin oxide, which although has the same properties, but consists of better available materials and is therefore cheaper. The solution was found in two metals called strontium – and Calciumvanadat. Metals such as gold or silver conduct electricity by along will be activated on the outer electrons of the metal atoms. The electrical charge can move so freely in the metal. However, in two used metals, cargo moves through a “hole” in the metal. This is not a hole in the physical sense, but to a positively charged metal zone, through the load like a liquid. This line property is essential in the production of displays.
