Tetracene Based OTFT with Nd2O3-dielectric Layer

1T1R Nonvolatile Memory with Al/TiO2/Au and Sol-Gel-Processed Insulator for Barium Zirconate Nickelate Gate in Pentacene Thin Film Transistor

A one-transistor and one-resistor (1T1R) architecture with a resistive random access memory (RRAM) cell connected to an organic thin-film transistor (OTFT) device is successfully demonstrated to avoid the cross-talk issues of only one RRAM cell. The OTFT device, which uses barium zirconate nickelate (BZN) as a dielectric layer, exhibits favorable electrical properties, such as a high field-effe...

Effects of Nd2O3 and TiO2 Addition on the Microstructures and Microwave Dielectric Properties of BaO-Nd2O3-TiO2 System

Molecular Self-Assembled Monolayers and Multilayers for Organic and Unconventional Inorganic Thin-Film Transistor Applications

Principal goals in organic thin-film transistor (OTFT) gate dielectric research include achieving: (i) low gate leakage currents and good chemical/thermal stability, (ii) minimized interface trap state densities to maximize charge transport efficiency, (iii) compatibility with both pand nchannel organic semiconductors, (iv) enhanced capacitance to lower OTFT operating voltages, and (v) efficien...

Field-effect transistors made from macroscopic single crystals of tetracene and related semiconductors on polymer dielectrics

We report properties of devices made by the adhesion of semiconductor crystals, including several tetracene specimens, to polymer gate dielectrics along with measurements of tetracene crystals on conventional Si/SiO2 dielectric surfaces. For the best tetracene, pentacene, and alpha-6T devices, mobilities exceeding 0.1 cm/V were measured, correlating well with expectations based on the literatur...

Plasma-polymerized multistacked bipolar gate dielectric for organic thin-film transistors

A 10-layer stack of bipolar gate dielectric was formed by sequential layer-by-layer deposition using pulsed radio frequency (RF) plasma polymerization of allylamine and vinyl acetic acid monomers. Due to polar groups localized at the interfaces between each consecutive layer by alternating amine (–NH2) and carboxylic acid (–COOH) functional groups, a 60 nm thick multilayer structure demonstrate...
