(author), Gelinck, G.H. (author), van Roermund, A. (author), Cantatore, E. (author)Amorphous Gallium-Indium-Zinc-Oxide (GIZO or IGZO) has been recently proposed [1] as an interesting semiconductor for manufacturing TFTs because of its mobility (μ∼20cm 2/Vs), superior to other common materials for large-area electronics like organic semiconductors and a-Si (μ∼1cm 2/Vs). The amorphous nature of GIZO grants also a good uniformity...conference paper 2012

(author)The first dual-gate thin-film transistor (DGTFT) was reported in 1981 with CdSe as the semiconductor. Other TFT technologies such as a-Si:H and organic semiconductors have led to additional ways of making DGTFTs. DGTFTs contain a second gate dielectric with a second gate positioned opposite of the first gate. The main advantage is that the...article 2011
