Strategies for Incorporation of Chalcohalide Nanomaterials into the Functional Devices

Abstract

AbstractIn the last decade, the outstanding optical, piezoelectric, pyroelectric, and photovoltaic properties of the chalcohalide nanomaterials have been demonstrated. The unique features of the one-dimensional antimony sulfoiodide (SbSI), antimony selenoiodide (SbSeI) and bismuth sulfoiodide (BiSI) make these nanomaterials attractive for application in different devices, such as photodetectors, solar cells, piezoelectric energy harvesters, pyroelectric nanogenerators, radiation detectors, and gas nanosensors. The chalcohalide nanomaterials can be incorporated into the functional devices using solution processing of the thin films, spin-coating deposition, films drop-casting, the compression of the nanowires under high pressure, hot pressing, and the alignment of the nanowires in the electric field. The main advantages and major limitations of the aforementioned processing methods are discussed in this chapter.KeywordAntimony sulfoiodide (SbSI)Antimony selenoiodide (SbSeI)Solution processingSpin-coatingDrop-castingCompression of the nanowiresSinteringNanowires alignment
