## Summary

The Cardiff University is seeking suppliers for the procurement of 6 epitaxial wafers of In(Ga)As Quantum Dots for research purposes. The university plans to use these wafers in the development of lab-on-chip optical biosensors, aiming to enhance their research activities and support future grant applications. The procurement falls under the goods category and is currently in the tender stage, with a deadline for submission set for September 14, 2022. Interested parties can find more details on the Cardiff University Procurement Services website.

This tender from Cardiff University provides an opportunity for suppliers in the semiconductor industry to compete for a contract that focuses on providing unique electronic and optical properties through compound semiconductors. Businesses specializing in semiconductors, particularly In(Ga)As and AlGaAs quantum dots, as well as optoelectronic devices manufacturing, are well-suited to participate in this tender. The open procurement method allows for multiple suppliers to bid, aiming to encourage a competitive environment and result in the selection of the most suitable supplier for the university's research needs.

## Notice

Cardiff University, School of Biosciences intends to purchase 6 epitaxial wafers of In(Ga)As (Indium Gallium Arsenide) quantum dots emitting at 1300nm embedded in a AlGaAs (Aluminium Gallium Arsenide)/GaAs (Gallium Arsenide) for the research activity of the QOBI team.Compound semiconductors, such as GaAs, In(Ga)As and AlGaAs, combine unique electronic and optical properties which make them ideal candidate for optoelectronic devices. For example, In(Ga)As QD are routinely used as active material in lasers and photodetectors.The procurement of the wafers will allow the QOBI team to progress in their research activity in the development of a lab-on-chip optical biosensor based on photonic devices fabricated from the supplied wafers. The devices will be fabricated at the cleanroom of the Institute of Compound Semiconductors.Demonstrating the operation of the biosensor device for the sensing of biological molecules, will support applications for future grants and external collaboration.NOTE: To register your interest in this notice and obtain any additional information please visit the Sell2Wales Web Site at https://www.sell2wales.gov.wales/Search/Search_Switch.aspx?ID=124093.
