Low-temperature metal–oxide thin-film transistor technologies for implementing flexible electronic circuits and systems

Abstract

Here we review two 300 °C metal–oxide (MO) thin-film transistor (TFT) technologies for the implementation of flexible electronic circuits and systems. Fluorination-enhanced TFTs for suppressing the variation and shift of turn-on voltage (V ON), and dual-gate TFTs for acquiring sensor signals and modulating V ON have been deployed to improve the robustness and performance of the systems in which they are deployed. Digital circuit building blocks based on fluorinated TFTs have been designed, fabricated, and characterized, which demonstrate the utility of the proposed low-temperature TFT technologies for implementing flexible electronic systems. The construction and characterization of an analog front-end system for the acquisition of bio-potential signals and an active-matrix sensor array for the acquisition of tactile images have been reported recently.

“…Flexible and stretchable nano materials are desired in many advanced applications, such as biomedical applications, 37 thermal management layers, 38 portable nanogenerators, 39 and electronic components. 40–43 Therefore, the insights gained here will facilitate the integration of 2D Re dichalcogenides into such applications.…”

Synthesis and Characterization of a Semiconductor Diodic Bilayer PbS/CdS Made by the Chemical Bath Deposition Technique

“…Semiconductors are also used as potentiometers in the automotive sector, as a portable semiconductor refrigeration device, as well as in thin-film transistors (TFTs), which are of high interest for further investigation and application due to their ease of fabrication . Flexible oxide TFTs are used as memristive devices, p-type tellurium (Te) TFTs, indium oxide (In 2 O 3 )-based TFTs, and TFTs based in metal oxide semiconductors in emerging applications such as flexible–stretchable devices; biosensors; zinc tin oxide, indium gallium zinc oxide, indium tin zin oxide, nitrogen-doped indium tin oxide, and indium tin oxide (ITO) TFTs as promising biosensing devices; and so on as next-generation TFTs, among others. − Solar energy is a freely available renewable energy source. Moreover, it is eco-friendly and can provide energy at a low cost.…”
