  • OXIDE SEMICONDUCTOR THIN-FILMS WITH CONTENT GRADIENT
    Publication number: 20200303555
    Abstract: An electronic device includes a first electrode, and a second electrode spaced apart from the first electrode. The electronic device further includes a conduction channel in electrical connection with the first and second electrodes so as to be able to conduct a charge carrier current between the first and second electrodes along a condition path during an operating condition. The conduction channel has a gradient semiconductor oxide composition transverse to the conduction path such that the gradient semiconductor oxide composition varies from indium rich to gallium rich.
