In this work, we investigated the use of a homogeneous Al-doped zinc oxide (AZO) buffer layer to improve the performance of an organic light-emitting diode (OLED) device fabricated on an AZO anode. For this, 10-nm-thick AZO buffer layers with Al doping concentrations of 3.1, 4.1, and 5.1 at % were grown on 140-nm-thick AZO anode films containing 2.1 at % Al(More)
As we are encountering to the aging society, the interest of serious games gets increasing. In this respect,‘SqueeView’ is aimed at enhancing visuo-spatial cognition of the elderly. In an empirical study with 35 mature adults, it was revealed that SqueeView had a significant effect for improving their visuo-spatial cognition capability. However, the(More)
