Carbononics (January 2016)

Guest edited by Pawel Hawrylak, Francois Peeters, and Klaus Ensslin

Carbononics – integrating electronics, photonics and spintronics – is about creating artificial materials with graphene quantum dots. For photonics, one can convert graphene, a semimetal, into a semiconductor with widely tunable bandgap. Continuously varying the lateral size of graphene quantum dots results in emitted light with energy and color ranging from THz to UV, as shown in the figure on the front cover and discussed by Ozfidan et al. (see their Review @ RRL on pp. 102–110).
The optical properties can be further integrated with electronic and magnetic properties by controlling the lateral size, shape, character of edge, sublattice symmetry, strain, number of layers, and carrier density as discussed in the contributions to this Focus Issue (cf. the Preface on pp. 11–12).

Functional Oxides (Juni 2014)

Guest edited by Jan M. Knaup, Thomas Frauenheim, Peter Broqvist, and Shriram Ramanathan

Oxide materials might form the basis for the next technological revolutions in fields such as electronics, photovoltaics or heterogeneous catalysis by enabling the production of inexpensive, high capacity and fast nonvolatile memories, neuromorphic computers and control systems, and efficient energy conversion devices. All these possible applications have in common that they promise to expand the limits of existing technologies by exploiting the inherent material-level complexity of oxides. (Read full text here)

Semiconductor Nanowires (October 2013)

Guest edited by Chennupati Jagadish, Lutz Geelhaar, and Silvija Gradecak

Semiconductor nanowires are structures that are characterized by their high aspect ratio and a diameter that typically does not exceed 100 nm. The nanoscale size and the quasi one-dimensional shape offer unique opportunities to control properties of semiconductors such as density of states, transport of electrons, and interaction with photons. Thus, these objects are considered as building blocks for the next generation of electronics, photonics, energy, sensing, and biomedical applications. Another important feature of nanowires is the possibility to grow hetero-structures of materials with large lattice and thermal mismatch without creating dislocations. (Read full text here)

Topological Insulators – From Materials Design to Reality (February 2013)

Guest edited by Claudia Felser, Shou-Cheng Zhang, and Binghai Yan

Topological insulators (TIs) are a new quantum state of matter discovered in recent years. They are beyond the spontaneous symmetry-breaking description by Landau and are instead characterized by topological invariants, and described by topological field theory. Their topological nature is similar to the quantum Hall effect, a major discovery of condensed-matter physics in the 1980s (Klaus von Klitzing, Nobel Prize in Physics, 1985). The manifestation of the topological effect is the existence of robust gapless surface states inside the bulk energy gap. The topological surface states exhibit Dirac-cone-like energy dispersion with strong spin-momentum locking. Potential future applications cover areas such as spintronics, thermoelectrics, quantum computing and beyond. (Read full text here)

Spintronics and Spin Physics (December 2011)

Guest edited by S. N. Piramanayagam, Jagadeesh Moodera, Russell Cowburn, and Rachid Sbiaa

The term spintronics has gained a considerable popularity recently. Albert Fert and Peter Grünberg received their Nobel Prize in 2007 for their discovery of Giant Magnetoresistance (GMR). Read sensors based on the concept of GMR in the late nineties and tunnel magnetoresistance (TMR) since the past several years, are utilized in hard-disk drive products. The field of spintronics from the early stages of GMR further flourished with the discovery of TMR as well as spin-torque transfer (STT) effect to switch magnetization or to move domain walls. These led to research in the areas of spin injection and manipulation in semiconductors, magnetic random access memory, magnetic logic devices, domain wall memory, and so on. As a result there are plenty of researchers all over the world pushing the frontiers in applied as well as fundamental aspects of the field. (Read full text here)

Sustainable Electronics (September 2011)

Guest edited by Peter J. Klar and Bruno K. Meyer

Today’s society uses up to 35 tons of material per capita and year for basic needs, luxury or consumer goods, hightech products, etc. Much of it is used in form of functional materials employed in highly specialized devices such as mobile phones. Cumulated sales up to 2008 correspond to 7.2 billions of mobile phones. A new generation of mobile phones comes up every half a year. More than 30 different metals are employed in this device and are essential for its functioning. The fraction of some of these metals in a mobile phone is higher than the typical content in corresponding mineral ores. (Read full text here)

Plasmonics and Nanophotonics (October 2010)

Guest edited by Stefan Maier

Plasmonics is rapidly developing into its own discipline at the boundaries of physics, materials science and chemistry, and leading the way towards a marriage between photonics and the nanosciences. A fascinating aspect of this field is its ability to bring together scientists working on the fundamentals of light/matter interactions in nanoscale systems and tool-makers aiming to utilize plasmonic systems for applications in the sciences and engineering.

Carbon Electronics: Graphene – Nanotubes – Diamond (September 2009)

With Guest Editorial by John Robertson

Carbon has three allotropes, each of which has been a star material at the time. Graphene, consisting of single layers of sp2 carbon, is presently the most exciting form of carbon, ever since it was made by the mechanical exfoliation of graphite by A. K. Geim et al. Its unique band structure of mass-less Fermions due to the Dirac cone structure, and the possibility of huge carrier mobilities with inhibited carrier scattering has led to intense fundamental research activity. The gap-less band structure requires the two carbon atoms in the planar unit cell to be symmetry equivalent, unlike in the Bernal graphite structure. (Read full text here)

Thermoelectrics (November 2007)

With Guest Editorial by Terry M. Tritt

Thermoelectric (TE) materials and devices are a solid-state technology that has been in use for decades, but research has been rapidly expanding over the last ten years. The primary reason is that these materials are of great technological importance and could provide significant contributions as alternative energy materials. In addition to waste heat recovery, TE materials are part of solid-state devices that could convert solar energy directly into electricity. (Read full text here)
