Diamond and 2D material heterostructures as a platform for room temperature detection of gases
Original language description
Heterostructure 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.
