Title: | Al2O3/CuO non-planar heterostructures for VOCs vapors detection | Authors: | MAGARIU, Nicolae ABABII, Nicolai POSTICA, Vasile BODDULURI, Mani LUPAN, Oleg ADELUNG, Rainer HANSEN, Sandra |
Keywords: | heterostructures;gas sensor;volatile organic compounds;metal oxide | Issue Date: | 2021 | Source: | https://doi.org/10.52326/ic-ecco.2021/EL.03 | Conference: | The 11th International Conference on Electronics, Communications and Computing | Abstract: | In this work, the gas sensing properties of the non-planar heterostructures based on CuO thin films, grown by the direct ink writing and covered with an ultra- thin Al2O3 layer, are presented as a function of the operating temperature. The obtained results demonstrates the excellent selectivity to volatile organic compounds (VOCs) vapors, namely n-butanol and 2-propanol in a operating temperature range of 200 – 350 oC. The relatively low gas response was observed at room temperature, which is very important for low-power operation. The dynamic gas response showed an ultra-fast response time of 2 – 3 s. The obtained results demonstrates the excellent potential of non- planar heterostructures based on metal oxides for use in high-performance environmental monitoring applications. |
