Crystal phases in III-V materials

We are surrounded by an ever-increasing flow of information. We don´t want to wait for information from Googleetc. and don´t want streamed videos to hack. We have seen an evolution from VHS to 4K video.

This drives thedevelopment of higher data transfer speeds, which places greater demands on the electronics that take care ofthe transfer.

For a long time, the semiconductor industry has refined existing concepts through evolution, but tocontinue development, a revolution is needed, a new way of thinking about how to design components.The project aims to investigate new ways of creating fast components. Conventionally, structures are made withthin layers with different compositions of atoms.

We will instead use the same atomic combinations, but withdifferent crystal phases, different ways of arranging the atoms in the material.

Carbon can e.g. occur in differentphases such as both diamond (hard) and graphite (soft).We will use a method to create these components that is based on a recently developed technology to createperfect structures with different phases, something that few laboratories can do today. This technology maybecome significant not only for components but also for studies of fundamental physics.

We will be able to studyphenomena that today can only be studied at extremely low temperatures, fractions of a degree above absolutezero, but at a temperature of 20 degrees that is much easier to achieve.
