Special Issue Information
Semiconductor metal oxide is a popular and important gas-sensitive material with applications in public safety, pollution monitoring, breath analysis, smart homes and automobiles. Metal oxide semiconductor nanomaterials, such as SnO2, ZnO, VO2, In2O3, WO3 and CuO, have a high sensitivity, short response/recovery time and low cost considering their large surface-area-to-volume ratio and activity. Obvious depletion layer form on the surface of nanomaterials when gas absorbs there. The sensitivity of nanomaterials can be improved by reducing them to an ultrathin nanosheet or ultralong nanowire composite with another metal oxide or noble metal to form a heterojunction. These strategies can increase the ratio of the depletion layer on the nanomaterial and produce new functional materials for high-performance device or sensor applications.
Significant efforts thus far have focused on the synthesis and characterization of metal oxide nanostructures, such as ultrathin nanosheets, nanowires, nanoparticles, nanorods and so on. Many of these have been used to fabricate composite structures, for example, nanoparticles on nanowire or nanorods, cross-linked nanowire, vertical nanosheet arrays, etc. The underlying physics of nanomaterials and their possible applications in various gas detections, electronic nose and chemiresistive gas sensors have attracted the attention of both theorists and experimentalists.
The present Special Issue aims to collect state-of-the-art work on semiconductor nanomaterials and their homo- or heterojunctions considering both fundamental and application perspectives. Review articles or research papers dealing with the fabrication and the gas sensing properties of semiconductor nanomaterials and their heterojunctions are welcome.
