Atomic fraction of ZnO and as a function of position on the wafers.
A saturation transfer curve demonstrating the method used to find carrier mobility, threshold voltage and subthreshold slope. The device in this figure has a composition of .
Mobility as a function of zinc oxide fraction across an entire wafer of devices. Note that the line serves as a guide to the eye only.
Threshold voltage and on/off ratio as a function of zinc oxide fraction across an entire wafer of devices. The sudden decrease in both threshold voltage and on/off ratio is due to the light sensitivity of these devices.
