Indium-gallium-zinc oxide ceramics are used as the backplane for flat-panel displays. A team of researchers reports the synthesis of centimeter-scale single crystals of a particular type of these semiconductors, InGaZnO4 (IGZO-11), with attractive characteristics such as wide band gap and high electrical mobility and conductivity, which make it promising candidates for transparent optoelectronic devices like touchable displays and organic LEDs.
