    AnnotationHeterostructure composite sensors utilize different parameters, resulting in improved response, selectivity, and reproducibility compared to pure materials. Ensuring clean air is fundamental for upholding a favorable quality of life on Earth. Supporting that knowledge, we present here an advanced material platform for room temperature conductivity gas sensors based on H-NCD films combined with a second gas-sensitive material, such as MoS2, rGO, SH-GO, or Au NPs. This platform supports the knowledge of gas sensing technology. Most of these diamond-based heterostructures based on diamonds exhibited improved gas sensing parameters and demonstrated a significant electrical response to gases at room temperature. In particular, the combination of SH-GO / H-NCD (two p-type materials) showed up to 630 % response for ethanol vapor. The synthesis of individual layers and measurement of sensor parameters are presented, and comparison and critical evaluation of responses.
