摘要

SrTiO3 (STO)-based all-solid-state electric-double-layer transistors (EDLTs) with a Li4SiO4 (LSO) lithium ion conductor (i.e., electrolyte) or Y-stabilized-ZrO2 (YSZ) proton conductor were fabricated. While the LSO device showed significant drain current enhancement at room temperature, the YSZ device needed high temperature to achieve comparable drain current enhancement due to the difference in ionic conductivity between the two electrolytes. Subthreshold swing (S), which is a parameter used to evaluate the steepness of drain current enhancement in field-effect transistors (FETs), was calculated to be 66 and 227mV/dec, respectively, for LSO and YSZ EDLTs. The 66mV/dec is very close to the theoretical limit (60mV/dec) for conventional FETs, indicating that LSO is more suitable for STO-based EDLTs and that the type of solid electrolyte used greatly affects EDLT switching characteristics.
