The influence of terminal alkyl groups on the structure, and electrical and sensing properties of thin films of self-assembling organosilicon derivatives of benzothieno[3,2-b][1]benzothiophene

Abstract

The synthesis and systematic investigation of organosilicon derivatives of benzothieno[3,2-b][1]benzothiophene (BTBT) with different length of terminal alkyl groups (from C2 to C13) or without it capable to self-assembly on the...

Discriminative Analysis of NOx Gases by Two-Dimensional Violet Phosphorus Field-Effect Transistors

“…The sensing mechanism of the FET gas sensor is based on the conductivity change of the semiconducting channel of an FET device during gas adsorption. , This offers an FET sensor with a very fast response (detection time on the order of seconds) and ultrahigh sensitivity, whose performance depends on the channel material. Inorganic two-dimensional (2D) nanomaterials, e.g., graphene, , MoS 2, , black phosphorus, , Ti 3 C 2 T x , , and organic polymers − have been applied to construct the semiconducting channel in FET gas sensors due to their unique structures and excellent electronic properties, which enables gas detection at room temperature and have a very low limit of detection (LOD).…”
