Materials for information and communication technologies

Information and communication technologies (ICT) require a diverse range of materials to function. Some of the essential materials used in ICT research at KTH include semiconductors, conductors, insulators, and magnetic materials.

Semiconductors such as silicon are used extensively in computer chips and electronic devices, while conductors like copper and aluminum are used to transmit electrical signals. Insulators like ceramics are utilized in electrical insulation applications. Magnetic materials are used in data storage and communication technologies such as hard disk drives and magnetic tapes.

Other materials used in ICT include optical fibers, which are used in telecommunications, and polymers, which are used in flexible displays and electronics. As the demand for faster and more efficient ICT continues to grow, the development of new materials and the optimization of existing ones will remain crucial. The emerging family of 2D materials, such as graphene, transition metal dichalcogenide monolayers, and MXene, is expected to play an increasingly important role in ICT techonolgies.
