Abstract for Presentation

 Metal Oxides: the demand for the Green Electronics of our future



Oxide electronic materials is one of the most promising technologies for electronic devices, as distinct from the traditional silicon technology. Metal-oxide semiconductors have attracted considerable attention over the past few decades because of their high transparency, large area, and mass production compatibility. Metal oxide-based thin film transistors (TFTs) have attracted interest for next-generation TFTs in foldable, flexible, and stretchable displays and transparent electronics. However, the common semiconductor used contains indium, such as IGZO, ITO, and IZO, are limited due to their environmental issues (i.e., toxicity), and high cost of indium. Therefore, there has been considerable research on transparent metal-oxide semiconductor electronic devices using low toxicity and abundant materials (zinc and tin), besides focusing research at nanoscale devices for a plethora of applications, including memories.

Also, a massive increase of the internet of things (IoT) nodes is happening nowadays, since almost every device has embedded electronics. However, this will induce a high quantity of electronic waste (e-waste) accumulation. To overcome this serious societal problem, it is necessary to rethink the production process of some electronic devices and to reconsider their environmental footprint. By adopting more abundant metal oxides and processes, electronics waste is reduced, leading to the reduction of the carbon footprint. Printed and paper electronics fulfil these requirements and have been considered as key to surpass the high production costs, material’s waste and still allow large area production.

In this work we will present the most important landmarks achieved by these stimulating scientific areas as well as some insights to emerging applications such as green electronics.
