Hydrogen Bistability as the Origin of Photo-Bias-Thermal Instabilities in Amorphous Oxide Semiconductors

The lack of transparency and high temperature processing in silicon-based electronics prevent their applications in transparent Zinc-based metal oxide semiconductors have attracted attention as an alternative to current silicon-based semiconductors for applications in transparent and fl exible electronics. Despite this, metal oxide transistors require signifi cant improvements in performance an...

Effect of enhanced-mobility current path on the mobility of AOS TFT

In this study, the mobility enhancement in an Amorphous Oxide Semiconductor Thin Film Transistor (AOS TFT), particularly the effect of enhanced-mobility current path was investigated. In the TFT structure, the a-IGZO single active channel layer was replaced by double layers. Indium Tin Oxide (ITO) was employed as an enhanced-mobility current path material and was embedded in an amorphous Indium...

Accurate modeling of amorphous Indium-Gallium-Zinc-Oxide TFTs deposited on plastic foil

Abstract—Amorphous Indium Gallium Zinc Oxide (a-IGZO) thin-film transistors (TFTs) are widely used in backplanes of high-definition displays thanks to the high field effect mobility of a-IGZO. To design high-performances and high-functionality a-IGZO circuits accurate physical modeling is required. In this work we propose a physically based analytical model of the drain current of a-IGZO TFTs. ...

Amorphous InGaZnO Thin Film Transistor Fabricated with Printed Silver Salt Ink Source/Drain Electrodes

Recently, amorphous indium-gallium-zinc-oxide thin film transistors (a-IGZO TFTs) with inkjet printing silver source/drain electrodes have attracted great attention, especially for large area and flexible electronics applications. The silver ink could be divided into two types: one is based on silver nanoparticles, and the other is silver salt ink. Organic materials are essential in the formula...
