The ability to control the semiconducting properties of Si on the nanometer scale promises a breakthrough in the development of Si-based technologies. In this paper, we present the results of our experimental studies of the photovoltaic effect in Ag2S QD/Si heterostructures in the short-wave infrared range. At room temperature, the Ag2S/Si heterostructures offer a noise-equivalent power of 1.1 x 10(-10) W/ radicalHz. The spectral analysis of the photoresponse of the Ag2S/Si heterostructures has made it possible to identify two main mechanisms behind it: the absorption of IR radiation by defects in the crystalline structure of the Ag2S QDs or by quantum QD-induced surface states in Si. This study has demonstrated an effective and low-cost way to create a sensitive room temperature SWIR photodetector which would be compatible with the Si complementary metal oxide semiconductor technology.", optnote="PMID:32365694; PMCID:PMC7712218", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=1151), last updated on Sat, 08 May 2021 20:03:22 -0500", issn="2079-4991", doi="10.3390/nano10050861", opturl="http://www.ncbi.nlm.nih.gov/pubmed/32365694", opturl="https://doi.org/10.3390/nano10050861", language="English" }
