Organic-polymer thin-film transistors for active-matrix flat-panel displays?

Sandrine Martin Michael Hamilton Jerzy Kanicki* Abstract — Organic-polymer-based thin-film transistors (OP-TFTs) look very promising for flexible, large-area, and low-cost organic electronics. In this paper, we describe devices based on spin-coated organic polymer that reproducibly exhibit field-effect mobility values around 5×10–3 cm2/V-sec. We also address fabrication, performance, and stabil...

P-102: Amorphous Silicon Thin-Film Transistors-based Active-Matrix Organic Light-Emitting Displays

In this paper, we describe hydrogenated amorphous silicon (a-Si:H) thin-film transistor (TFT)-based active-matrix arrays for active-matrix organic light-emitting displays (AM-OLEDs). The proposed pixel electrode circuits based on three a-Si:H TFTs can supply a continuous output current for AM-OLEDs. Each pixel circuit has compensation circuits that can adjust for the OLED and a-Si:H TFTs electr...

Organic polymer thin-film photo-transistors

We have investigated the effects of illumination, both broadband and monochromatic, on the electrical performance of organic polymer thin-film transistors (OP-TFTs). In each case, providing the illumination is sufficiently absorbed by the organic polymer, the drain current of a device biased in the OFF-state is significantly increased. We have observed increases in the OFF-state drain current a...

Process Optimization of Deposition Conditions for Low Temperature Thin Film Insulators used in Thin Film Transistors Displays

Deposition process for thin insulator used in polysilicon gate dielectric of thin film transistors are optimized. Silane and N2O plasma are used to form SiO2 layers at temperatures below 150 ºC. The deposition conditions as well as system operating parameters such as pressure, temperature, gas flow ratios, total flow rate and plasma power are also studied and their effects are discussed.  The p...
