Extended Data Fig. 7: Comparison of SiO2-gated IGZO transitor fabricated with silk and commercial surfactant-added aqueous precursor solution.
From: Silk fibroin as a surfactant for water-based nanofabrication
a, b, Digital (left) and microscope images (middle and right) of fabricated IGZO device using SDS or SF30 at the concentration of 0.01 w/v% (for a) and 0.1 w/v% (for b). Middle microscope image shows low magnification top view (x5 objective lens), and right microscope image shows enlarged IGZO channel morphology (x20 objective lens, scale bar is 200 μm). c, Schematic illustrating device structure and characterization setup. d, e, transfer curve of fabricated IGZO transitor with 0.01 w/v% (for d) or 0.1 w/v% (for e) of surfactant. Data represented as only mean (n = 3).
