Researchers from the University of Minnesota have discovered a new nano transparent scale film material with the highest conductivity in its class. The new material that they discovered can make electronics faster and smaller. They are trying to research the transparent technology and use it to make powerful transparent electronic devices.
Is there a way to make transparent electronic devices or there is more resource needed on transparent technology?
The discovery is being published today in Nature Communications, an open access journal that publishes high-quality research from all areas of the natural sciences. This new material so unique because it has a high conductivity, which makes electronics more powerful. The material also has a transparent look, which means light can pass through the material making it transparent. Materials with a wide band-gap, usually have either low conductivity or poor transparency. “The high conductivity and wide band-gap make this an ideal material for making optically transparentdevices and conducting films which could be used in a wide variety of electronics.Bharat Jalan the professor and the lead researcher of University of Minnesota chemical engineering and materials science wants to make the transparent technology even better than now.
Can transparent technology be used now or in the distant future?
Currently, most of the transparent technology in our electronics use a chemical element called indium. The price of indium has gone up tremendously in the past few years significantly adding to the cost of current transparenttechnology. There has been an effort to find alternative materials that can be used in transparentdevices that work as well as indium-based transparent conductors. In this study, researchers found a solution. They developed a new transparent conducting thin film using a novel synthesis method. Using this method they grew a BaSnO3 thin film and replaced elemental tin source with a chemical precursor of tin. Both barium and tin are significantly cheaper than indium and are abundantly available and can make the transparent electronic devices easier to make and at the same time cheaper.
Can transparent technology be improved and how can scientists manage that
Jalan and Prakash said this new process allowed them to create this material with unprecedented control over thickness, composition, and defect concentration. The new process is also reproducible and scalable. They want to improve defects concentrations that allowed them to discover high conductivity in the material. The next step for the scientists is to continue to reduce the defects and making the transparent technology even better. “Even though this material has the highest conductivity there is much room for improving the transparent technology, of the potential for discovering new things. That’s our next goal,” Jalan said.
