Amorphous thin-film-transistors

Fig. 4. Some electronic device applications using amorphous silicon (a) solar cell, (b) thin-fiLm transistor, (c) image sensor, and (d) nuclear particle detector.

As described earlier, the covalently bonded hydrogen, by passivating dangling bond defects and removing strained weak Si—Si bonds from the network, dramatically improves the semiconducting quality of amorphous silicon. Hence without the presence of hydrogen, effective amorphous semiconductor devices such as solar cells or thin film transistors would not be possible. Unfortunately, low defect density, high electronic quality...

Thin film transistors (TFTs) based systems are much better for colour displays since they give better viewing angles, response times and resolution than STNs. Those systems in which an array of amorphous siUcon transistors is vapour-deposited onto one side of the substrate, each transistor being positioned below each pixel, are known as active matrix TFT (AMTFT) displays.
