Copper Monosulfide Powder / CuS Powder (CuS, 15um, 99%)

Copper Monosulfide Powder

Copper monosulfide powder is a binary compound composed of copper (Cu) and sulfur (S). It is one of the most stable forms of copper sulfide, and its powdered form is a black or dark gray substance. Copper monosulfide exists in several polymorphs, with chalcocite being the most common and stable one. The material is of significant interest in various scientific fields due to its unique electronic properties, semiconducting behavior, and chemical reactivity.

Properties

Copper monosulfide powder exhibits several unique properties that contribute to its usefulness in a variety of applications:

Semiconducting Properties: CuS is a p-type semiconductor, meaning it has a relatively high concentration of holes (positively charged carriers). This property makes copper monosulfide an attractive material for use in electronic and photovoltaic applications.

High Surface Area: As a fine powder, CuS has a large surface area to volume ratio, which enhances its reactivity and catalytic properties. This feature is particularly valuable in applications such as energy conversion and chemical sensing.

Optical Properties: Copper monosulfide has distinctive optical characteristics, including absorption in the infrared and visible regions of the spectrum.

Applications

Energy Conversion and Storage

Solar Cells and Photovoltaics: CuS is being studied for use in solar cells and photovoltaic devices due to its semiconducting properties. It can be used as an electrode material or a light absorber in thin-film solar cells, helping convert sunlight into electrical energy. Its high absorption capacity in the infrared spectrum can be advantageous in the design of solar energy harvesting systems.

Supercapacitors and Batteries: Copper monosulfide powder can be used in energy storage devices, particularly in supercapacitors and batteries. Its high surface area and electrochemical properties make it an excellent candidate for enhancing the performance of energy storage systems by improving charge capacity and cycling stability.
