Webb13 apr. 2024 · Highly stable metal oxide thin film transistors (TFTs) are required in high-resolution displays and sensors. Here, we adopt a tantalum cation (Ta5+) doping method to improve the stability of zinc–tin–oxide (ZnSnO) TFTs. The results show that Ta5+-doped TaZnSnO TFT with 1 mol% concentration exhibits excellent stability. … WebbGold can be colored by creating surface oxide layers. Because gold does not oxidize in its pure form, base metals have to be added to create blue, brown, and black gold. The "Hearts" collection, in blue gold, is by Ludwig Muller of Switzerland. Crosses of black gold may be colored in different ways, as shown above.
