Copper Oxide Thin Films, Nanoparticles, and Hybrid Bonding
This community develops copper oxide thin films and nanoparticles for solar energy conversion, photocatalytic environmental remediation, and advanced semiconductor packaging.
The research focuses on synthesizing cuprous (Cu2O) and cupric (CuO) oxides using methods such as magnetron sputtering, spray pyrolysis, and hydrothermal synthesis. These materials are characterized for their structural, optical, and electrical properties, with specific applications in heterojunction solar cells, photocatalytic degradation of pollutants, and direct copper-to-copper hybrid bonding for chip integration. Doping with elements like zinc, magnesium, or aluminum is frequently used to tune these properties.
The largest share of the community's output is found in copper research, accounting for 80.0% of all copper research tracked in this group, which is also the element with the highest paper count within this community.
The community comprises 5,082 papers, publishing primarily in Thin Solid Films, Applied Surface Science, and Journal of Applied Physics.
Recent work continues to explore the synthesis of CuO/Cu2O nanoheterostructures for environmental applications and the development of Cu-Cu hybrid bonding technologies for 3D integrated circuits.
