The Effect of Gate and Drain Fields on the Competition Between Donor-Like State Creation and Local Electron Trapping in In–Ga–Zn–O Thin Film Transistors Under Current Stress PROJECT TITLE :The Effect of Gate and Drain Fields on the Competition Between Donor-Like State Creation and Local Electron Trapping in In–Ga–Zn–O Thin Film Transistors Under Current StressABSTRACT:Thin-film transistors (TFTs) based mostly on In-Sn-Ga-O (ITGO) semiconductors were evaluated with respect to totally different post-annealing temperatures (200 °C ~ 350 °C). High-performance devices were obtained, exhibiting field-effect mobility values exceeding 25 cm2/Vs at all thermal treatments. However, the edge voltage shift (AVth) beneath negative bias stress increased with increasing annealing temperature, that is opposite to what is usually observed in oxide semiconductor TFTs. It is instructed that annealing at elevated temperatures leads to comparatively massive concentrations of oxygen deficient sites in ITGO. These defects act as sources of excess electron carriers, that induce massive Vth shifts upon negative bias stress. Relatively low process temperatures are thus most well-liked in ITGO TFTs, that are anticipated to pave the method for the event of versatile displays. Did you like this research project?
