“…All of the above indicates that II-VI semiconductors, in their properties, in many cases, are analogues of metal oxides. This similarity explains why many attempts have been made in recent years to develop conductometric gas sensors based on them [39][40][41][42][43][44]. In addition, it has been established that II-VI semiconductor compounds have other properties that are important for gas-sensitive materials intended for use in conductometric gas sensors [45]:…”

“…Conductometric gas sensors based on ZnS, CdS, ZnSe, and CdSe, with high sensitivity to various gases can indeed be created. Currently, a fairly large number of articles and reviews have been published with research results in this area [29,[39][40][41][42][43][44]49]. The main results of these studies can be summarized as follows: [37,41,50].…”

“…As shown by Kumar et al [42], semiconductor-polymer nanocomposites can also be used to develop gas sensors based on II-VI compounds. Interest in such composites is due to the fact that by changing the amount and size of nanomaterials in a II-VI semiconductorpolymer composite, it is possible to achieve the increased sensitivity and selectivity of polymer gas sensors towards hazardous gases [102][103][104].…”

A review of the state of research in the development of conductometric gas sensors based on II–VI semiconductors is given. It was shown that II–VI compounds indeed have properties that are necessary for the development of highly efficient gas sensors. In this case, to achieve the required parameters, all approaches developed for metal oxides can be used. At the same time, during a detailed review, it was concluded that sensors based on II–VI compounds have no prospects for appearing on the gas sensor market. The main obstacle is the instability of the surface state, which leads to poor reproducibility of parameters and drift of sensor characteristics during operation.
