Organic Thin Film Transistor with Aligned Nanowires/Thin Film Hybrid Channel for Low-Concentration Detection of NH₃ at Room Temperature

ACS Applied Electronic Materials, Journal Year: 2024, Volume and Issue: 6(11), P. 8059 - 8067

Published: Oct. 21, 2024

An extremely sensitive ammonia (NH3) sensor was developed by using an aligned nanowires/thin film hybrid channel of organic thin transistor (OTFT). Conjugated polymer poly(2,5-bis(3-tetradecylthiophen-2yl)thieno(3,2-b)thiophene) (PBTTT-C14) has been used as semiconductor that fabricated via "floating transfer method" (FTM). The crystalline fibrillar microstructure within the liquid phase mixed solvent, which self-assembled on air–liquid interface through FTM method. This structured then transferred a cleaned Si/SiO2 substrate, whereas Au source–drain electrodes this OTFT. To investigate sensing behavior designed OTFT, various low concentrations NH3 have exposed ranging from 0.2 to 5 ppm. From accumulation mode drain current variation, it observed is toward gas with response about 75% at ppm, limit detection (LOD) ∼0.67 confirms its applicability lower concentrations. More interestingly, depletion OTFT reduces ∼200 times during investigation, ∼40 larger variation than current. Additionally, these variations excellent linearity concentration. also exhibits selectivity and sensitivity gas, can satisfy requirements for real-world applications.
