About the talk
Chemiresistive gas sensors based on metal sulfide materials have attracted significant attention due to their unique physical and chemical properties, cost-effectiveness, and abundance. Metal sulfides, such as copper sulfide (Cu₂S), often exist naturally as minerals like chalcocite, making them a readily available and economical option for sensor development. However, limited research has been conducted on their uses as gas sensor, the literature shows only few examples for detecting gases such as ammonia and ethanol.
My thesis focuses on synthesizing metal sulfides, including copper sulfide derived from metallic complexe as single source precursor (SSP) [Cu(Et4P2S2)Cl]2 to integrate them into the fabrication steps of electronic gas microsensors. These sensors are designed to detect various toxic gases and volatile organic compounds that are relevant for environment, security, and agriculture.
During the talk, more details about the synthesis, fabrication, and properties of copper sulfide are going to be presented.
