TaS3 Nanofibers: Layered Trichalcogenide for High Performance Electronic and Sensing Devices

Popis výsledku v původním jazyce

The layered materials like transition metal dichalcogenides exhibit broad spectra of outstanding properties with huge application potential, while another group of related materials, layered transition metal trichalcogenides remains unexplored. Here we show a broad application potential of this interesting structural type of layered tantalum trisulfide prepared in a form of nanofibers. This material shows tailorable attractive electronic properties dependent on the tensile strain applied to it. Structure of this so-called orthorhombic phase of TaS3 grown in a form of long nanofibers has been solved and refined. Taking advantage of these capabilities, we demonstrate highly specific impedimetric NO gas sensor based on TaS3 nanofibers as well as construction of photodetectors with excellent responsivity and field effect transistors. Various flexible substrates were used for the construction of NO gas sensor. Such device exhibits a low limit of detection of 0.48 ppb, well under the allowed value set by environmental agencies for NOx (50 ppb). Moreover, this NO gas sensor also proved excellent selectivity in the presence of common interferences formed during fuel combustion. TaS3 nanofibers produced in large scale exhibited excellent broad application potential for various types of devices covering nanoelectronic, optoelectronic and gas sensing applications.
