Enhancement-mode polymer space-charge-limited transistor with low switching swing of 96 mV/decade

Abstract

In this letter, an enhancement-mode polymer space-charge-limited transistor was realized with a low switching swing of 96 mV/decade, a low operation voltage of 1.5 V, and a high on/off current ratio of 10(4). By investigating the influence of the device's geometric parameters on the transistor characteristics, a low switching swing was obtained by positioning the base electrode at the middle of the channel length and reducing the opening diameter. Simulations of the potential distribution at the central vertical channel verified that the base electrode has the best control over the magnitude of potential barrier, resulting in a low switching swing.
