Neural networks are information processing models based on the human brain, and they have been activity studied. However, in order to realize the hardware of the neural network, it is necessary to achieve high integration. In this study, we fabricated synapses for neural networks using the Ga-Sn-O (GTO) thin films, which is rare-metal-free amorphous oxide semiconductor. The synapses are planar type,...
The flatpanel imager used for the new type magnifying viewer was able to detect the difference in brightness and succeed in character detection. However, the outline part of the character was blurred and the reading accuracy was low. In this research, a liquid crystal lens was used to reduce irregular reflection that is a cause of reduction in reading accuracy of the flat panel imager. As a result,...
Trap densities in the channel layers of ZnO thin-film transistors have been extracted. First, the low-frequency (low-f) capacitance–voltage – characteristics are measured using the customized measurement system. Next, the surface potential is calculated from the low-f – characteristic, and the surface potential gradient is calculated by applying Gauss's law. Finally, the spatial profile...
