Nanoscale devices based on artificial materials (TTF.5909)

Project nummer: ttf5909

Omschrijving van het onderzoek

The possibilities of designing and realizing materials with specific properties by atomic-scale tailoring their compositions open the way to novel nanoscale devices. With our controlled Pulsed Laser Deposition technique that includes several in situ diagnostic tools, such structures can be built with atomic precision and possess properties that surpass those of the individual building blocks. It also underlines the potential of designing artificial superlattices with unique properties.
For example, most ferromagnetic materials show no ferroelectricity. But what would a superlattice made from ferroelectric and ferromagnetic building blocks be like? Would it show ferroelectric or magnetic behaviour, or have a mix of properties?
New phenomena might even emerge. The developed technique is an invitation to materials scientists to design and build their own superlattice.
A potential application of ferroelectric materials lies in ultra-high-density memory devices, produced by controlling the ferroelectric domains at the nanometre scale3. Such storage devices would be non-volatile (and so able to retain the stored data for long periods of time without any power supply) and have short boot-up times.
