21 Jul 2017 Magnetic Skyrmions for Next-Generation Non-Volatile Memory

Magnetic skyrmions are nanoscale topological spin structures offering great promise for next-generation memory technologies. However, translating their promise into viable technology requires the ability to modulate skyrmion properties, and their electrical detection under ambient conditions. Researchers at DSI, NTU, and IHPC have developed a novel, CMOS-compatible thin film material platform that enables bottom-up control of skyrmion properties at room temperature. By varying the thickness of constituent layers, they could smoothly modulate the size, density, and stability of skyrmions. Through this, they could achieve skyrmion configurations tailored to contrasting device requirements - all while using industry-compatible fabrication techniques. In conjunction, the team also demonstrated the world-first electrical detection (Hall effect) of ambient skyrmions. This breakthrough development provides a stepping stone for realizing stable and highly scalable (down to 10nm and below) non-volatile memory. Their paper “Tunable room-temperature magnetic skyrmions in Ir/Fe/Co/Pt multilayers” was published in Nature Materials (Online) on 17 July 2017. Learn more:

25 Nov 2016 Review in Nature: Emergent phenomena induced by spin–orbit coupling at surfaces and interfaces

Substantial progress in the past decade in the fabrication and modelling of atomically precise interfaces and surfaces has led to the discovery of many electronic effects that are of interest for practical devices with novel functionalities. Christos Panagopoulos and colleagues review various such effects—and their technological potential—with a focus on the role of spin–orbit coupling, the fundamental interaction between the spin and charge degrees of freedom of an electron. Spin–orbit coupling can affect the electronic properties of materials at reduced dimensions, and the authors discuss the basic principles for understanding and engineering interfaces and surfaces in which spin–orbit coupling is harnessed. Examples are structures based on topological insulators where spin currents are generated or converted and magnetic layers where spin–orbit coupling leads to spin textures that can be controlled.

24 Nov 2016 Review in Science Mag: A Clear Approach to Nanophotonics

The resonant modes of plasmonic nanoparticle structures made of gold or silver endow them with an ability to manipulate light at the nanoscale. However, owing to the high light losses caused by metals at optical wavelengths, only a small fraction of plasmonics applications have been realized. Kuznetsov et al. review how high-index dielectric nanoparticles can offer a substitute for these metals, providing a highly flexible and low-loss route to the manipulation of light at the nanoscale.

09 Nov 2016 A*STAR Scientist, Dr Arseniy Kuznetsov clinched the prestigious international IET A F Harvey Engineering Research Prize 2016

A*STAR Scientist, Dr Arseniy Kuznetsov has clinched the prestigious international IET A F Harvey Engineering Research Prize 2016! His outstanding contributions to research in the field of Lasers and Optoelectronics, as well as pioneering research on dielectric nanoantennas has won him the accolade. Photonics, the science of light, is one of the most rapidly developing scientific fields resulting in a number of modern technologies, which have already become a part of our everyday life. Arseniy’s research will benefit the development of virtual and augmented reality devices, 3D holographic displays, among others. He will be presenting a Prize Lecture, ‘Novel resonant dielectric nanophotonics for novel technologies’ at The Institution of Engineering and Technology (IET) London next year in March.
