TL;DR: It is shown that when a solution processable organic semiconductor (6,13-bis(triisopropylsilylethynyl)pentacene) is blended with an insulating polymer (PS), morphological and structural characteristics of the blend films could be significantly influenced by the processing conditions like the spin coating time.

TL;DR: The results prove that reducing the substrate-induced doping of graphene with a polymer brush is a direct method for boosting the gas sensing properties of graphene FETs.
Journal ArticleDOI
NO2-Affinitive Conjugated Polymer for Selective Sub-Parts-Per-Billion NO2 Detection in a Field-Effect Transistor Sensor.
TL;DR: In this article, the same conjugated polymers with different side chains were adopted in the field effect transistor (FET) sensor for NO2 detection, and the response to NO2 showed an opposite tendency to the charge carrier mobility of each CP.
Journal ArticleDOI
Optimization of gate-bias stability and gas-sensing properties of triethylsilylethynyl anthradithiophene micro-strip field-effect transistors by incorporating insulating polymer
Do Hun Kwak,Hyun Ho Choi,John E. Anthony,Seung-Hyun Kim,Huijeong Chae,Jinhyun Hwang,Shichoon Lee,Hui Joon Park,Bong-Gi Kim,Wi Hyoung Lee +9 more
TL;DR: In this article, a binary blend film based on TES-ADT and insulating polymer was annealed by solvent vapor with patterned PDMS molds, which resulted in highly crystalline micro-strip films where TES and the insulating polyamide were phase-separated on top and bottom, respectively.
