Driven by the ever-increasing market demands in computing, communication, and multimedia applications, the microelectronics industry has got rapid development recently.
Because of innovations and advancements at almost every technological level, such as material, process, equipment, device, circuit and system, silicon-based logic and memory IC technologies continue to be the industry's R&D focus with nano-scaled scaling.
This gives a strong boost to the traditional "Moore's Law", which keeps on increasing the function density while reducing the cost per function in an IC and brings the R&D activities to a new level known as "More Moore". At the same time, a new trend in microelectronic industry, namely "More than Moore", has expanded the scope of IC applications by integrating non-digital functionalities into traditional CMOS micro-systems, thus enabling the deployment of innovative product solutions required by modern information world.
As the abovementioned amazing progress of microelectronics ongoing, the editorial board of SCIENCE CHINA: Information Sciences was highly motivated to publish a special issue to highlight the current developments within this exciting field. This special issue covers the advances in state-of-the-art development, grand challenges, innovative solutions, and broad scope of microelectronic technologies related to both "More Moore" and "More than Moore". The issue contains 14 invited papers from both industry (e.g., Intel, IBM, Applied Material, Macronix, etc.) and academic (e.g., Yale University, Peking University, UCLA, CEA-Leti, etc.), as the following:
• The driving force for development of IC and system in future: Reducing the power consumption and improving the ratio of performance to power consumption (invited)
• Variability in nanoscale CMOS technology
• Advanced strain engineering for state-of-the-art nanoscale CMOS technology
• Next-generation lithography for 22 and 16 nm technology nodes and beyond
• Inelastic electron tunneling spectroscopy (IETS) study of high-k gate dielectrics• Ultra-thin films and multigate devices architectures for future CMOS scaling

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
