Web7 jan. 2024 · Flexible ion-gated transistors showed good mechanical stability at different bending curvature radii and under repetitive bending cycles. The mobility of flexible ion-gated transistors remained almost unchanged upon bending. After 1000 bending cycles the mobility decreased by 20% of its initial value. Webdiscrimination during ion gating may be minimized, however, it is remains unclear how this behavior will translate to ion beam multiplexing approaches.
