Толуол и хлороформ – вредные неполярные газы, образующиеся в различных процессах горения и связанные с загрязнением воздуха и респираторными заболеваниями. Пористый кремний (ПС) показал многообещающие результаты в качестве материала для измерения газов аммиака и этанола. Однако существует потенциал для дальнейшего улучшения за счет оптимизации свойств их поверхности для приложений, связанных с измерением неполярного газа. Химическая обработка широко используется для модификации характеристик поверхности материалов, в том числе полупроводников, для различных применений. Мы нанесли слой никеля (Ni) на поверхность ПК с помощью химической обработки. Установлено, что чувствительность образца ПС, осажденного Ni, к концентрации 0,1 ppm паров неполярного толуола и хлороформа увеличилась с &lt;1 % до 39 % и 32,6 % соответственно по сравнению с ПС. Это исследование дает ценную информацию о методах модификации поверхности для повышения производительности газовых датчиков, что может оказать существенное влияние на разработку передовых сенсорных технологий для экологических и промышленных применений.</p></abstract><trans-abstract xml:lang="en"><p>Gas sensors are important devices in various industrial and environmental monitoring applications. Toluene and chloroform are harmful non-polar gases that are produced in various combustion processes and are associated with air pollution and respiratory diseases. Porous silicon (PS) has shown promising results as a material for ammonia and ethanol gas sensing applications. However, there is potential for further improvement by optimizing their surface properties for non-polar gas sensing applications. Chemical treatment has been widely utilized to modify the surface characteristics of materials, including semiconductors, for various applications. We have deposited nickel (Ni) layer on PS surface using chemical treatment. In comparison to the PS sample, it was discovered that the Ni-deposited PS sample was more sensitive to 0.1 ppm concentrations of non-polar toluene and chloroform vapours, increasing from 1% to 39% and 32.6%, respectively. This study provides valuable insights into the surface modification techniques for enhancing the performance of gas sensors, which can have a significant impact on the development of advanced sensing technologies for environmental and industrial applications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>газовый сенсор</kwd><kwd>пористый кремний</kwd><kwd>никель</kwd><kwd>химическая обработка</kwd><kwd>чувствительность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gas sensor</kwd><kwd>porous silicon</kwd><kwd>nickel</kwd><kwd>chemical treatment</kwd><kwd>sensitivity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chang T.Y., Singh A.K., Shao J.H., Huang C.Y., Shieh J.M., Wuu D.S., Horng R.H.
