Linearity of Hetero-Gate-Dielectric Tunneling Field-Effect Transistors

Linearity characteristics of hetero-gatedielectric tunneling field-effect transistors (HG TFETs) have been compared with those of high-k-only and SiO2-only TFETs in terms of IIP3 and P1dB. It has been observed that the optimized HG TFETs have higher IIP3 and P1dB than high-k-only and SiO2-only TFETs. It is because HG TFETs show higher transconductance (gm) and current drivability than SiO2-only...

Stable complementary inverters with organic field-effect transistors on Cytop fluoropolymer gate dielectric

We present results on small-molecule pand n-type organic semiconductors in combination with the highly water repellent fluoropolymer CytopTM as the gate dielectric. Using pentacene and N,N -ditridecylperylene-3,4,9,10-tetracarboxylicdiimide PTCDI-C13 , we fabricated complementary inverters of high electrical quality and stability that are almost unaffected by repeated gate bias stress. The comb...

Solution processable multi-channel ZnO nanowire field-effect transistors with organic gate dielectric.

The present work focuses on nanowire (NW) applications as semiconducting elements in solution processable field-effect transistors (FETs) targeting large-area low-cost electronics. We address one of the main challenges related to NW deposition and alignment by using dielectrophoresis (DEP) to select multiple ZnO nanowires with the correct length, and to attract, orientate and position them in p...
