Bottom-gate multi-channel ferroelectric-gate field effect transistors (FETs) based on ZnO nanofibers were fabricated, using Bi3.15Nd0.85Ti3O12 (BNT) thin film as the gate insulator and semiconductor multi-channel. The electrical characteristics of nanofiber FETs showed typical p-channel transistor properties with a low threshold voltage −0.5 V, high effective mobility, large on/off current ratio 104. These excellent performances are attributed to BNT insulator.

Abstract The open hole clad technology based on high performance solid expandable tubular is an innovative developed rapidly in recent years.
