Environmentally Sustainable Materials for Nanoelectronics

FRE is an innovative company creating new solutions for challenging problems.  Our researchers develop alternative materials for technologically important applications. Examples are sensors and actuators. We have several ongoing projects on thin films, nanoparticles and bulk ceramics. The ideas are tested and the best ones are patented and licensed. For prototype development and testing we collaborate with the best research centers. Materials are developed using state-of-the-art techniques, such as neutron and x-ray synchrotron diffraction, to explore their structural characteristics. Consequent tests include thin film growth and the studies of electrical and magnetic properties. Materials are compatible with prevailing semiconductor wafers.  

Permanent magnets and lasers utilize rare-earth elements (REE), such as neodymium and samarium. REE became to spotlight once there was a price peak in 2011. Though being central for the contemporary electronics they are by no means indispensable. We at FRE develop new rare-earth-free materials for applications requiring room-temperature permanent magnets. New materials have been developed and tested and several are currently under tests.

We have developed several electrically insulating ferromagnetic materials suitable for tunable rf-device and spintronic applications. To respond to tougher technological and environmental requirements multiferroic materials possessing coupled ferroic properties, such as ferroelectric and ferromagnetic, are under development. Our R&D focuses on cheap and non-toxic raw materials.

The R&D tasks are challenging and we apply state-of-the-art analytical tools, such as neutron scattering and diffraction, to understand the atomic scale structure behind the physical properties. Computational tools for modelling complex structures were developed and patented.

Ferroelectric Materials

FRE studies ferroelectric materials for memory cell applications. Recent research conducted with our collaborators shows that it is possible to preserve the crystallogaphical state even after the materials has been heated above the ferroelectric-paraelectric phase transition temperature. For memory cell applications this means that the component operation temperature range can be extented.

We develop Pb-free ferroelectrics. The European Union has set very strict limitations for the use of Pb and other toxic materials by RoHS directive.

 

Multiferroic Materials

Materials possessing coupled ferroelectric and ferromagnetic ordering belong to a class of multiferroic materials. Multiferroic materials have a great potential in tunable components, such as phase shifters and delay lines, as they allow smaller and faster components. FRE develops new multiferroic materials and several new compounds are currently being tested.  We have developed in collaboration with US National laboratories a new room-temperature ferromagnetic thin film material class. No REE, iron or toxic materials are applied. The material properties, including magnetism and crystal distortion can be controlled, which opens up ways to create microelectronic devices without abrupt interfaces. Detrimental dislocation and interface strain formation due to the lattice mismatch can be minimized or even avoided.
