See-through circuitry: New method makes AZO a viable and cheap alternative for transparent electronics Indium tin oxide (ITO) is the current material of choice for electronics because it combines optical transparency with electrical conductivity. Its use ranges from touch-sensitive smartphone screens to light-harvesting solar panels. Indium is in short supply, however, and as demand increases for ITO-containing devices, so does the price of indium.One promising low-cost ITO alternative is a transparent material known as aluminum-doped zinc oxide (AZO).“The elements that make up this material are more abundant than indium, making AZO a commercially sensible option,” said Professor Husam Alshareef from the KAUST Physical Science and Engineering Division who also led the research. “However, electronic devices made using AZO have traditionally shown inferior performance to devices made using ITO.” Read more. -- source link
