1D Hybrid Tin Oxide Nanostructures: Synthesis and Applications

Modeling the Conduction Mechanism in Chemoresistive Gas Sensor Based on Single-Crystalline Sn3O4 Nanobelts: A Phenomenological In Operando Investigation

“…Moreover, it was also applied to elucidate the lower sensor signals ( S ) observed in p-type semiconductors (CuO and Cr 2 O 3 ) compared to n-type semiconductors with similar morphological characteristics and depletion/accumulation layer dimensions ( S p ≈ S normaln ). − Nevertheless, given that the validation of the existing models is limited to sensitive layers composed of polycrystalline grains, investigation of the sensing phenomena occurring in alternative architectures is demanded. One-dimensional (1D) nanostructures, including nanowires, nanotubes, and nanobelts, have been particularly attractive building blocks for manufacturing advanced gas sensing devices due to the high surface-to-volume ratio and confined electronic transport in one direction. − Consequently, a comprehensive examination of the conduction process at their interfaces becomes essential for optimizing their sensing properties.…”
