[3] IGZO-TFT has 20–50 times the electron mobility of amorphous silicon, which has often been used in liquid-crystal displays (LCDs) and e-papers.
Power consumption is improved by LCD idling stop technology, which is possible due to the high mobility and low off current of IGZO-TFT.
The most widely used technique for transparent conducting oxide (TCO) synthesis is pulsed laser deposition (PLD).
The substrates are placed in a PLD vacuum chamber, which controls oxygen pressure in order to ensure favorable electrical properties.
While PLD is a useful and versatile synthesis technique, it requires expensive equipment and plenty of time for each sample to adjust to regular atmospheric conditions.
[13] One common type of combustion synthesis is spin coating,[14] which involves depositing In and Ga solution layers onto a hot plate and annealing at temperatures roughly between 200 and 400 degrees C, depending on the target composition.
