Einem Team von Forschern der Uni Hamburg und des spanischen Forschungszentrums IMDEA Nanoscience ist es gelungen, Materialien auf chemischem Wege herzustellen, die sich durch Selbstorganisation zu zweidimensionalen Nanostrukturen zusammenfinden.

Quantum dots have been receiving extensive attention from researchers because they can be widely used for basic physics study, quantum computing, biological imaging, nanoelectronics, and photonics applications. Current major fabrication methods for semiconductor quantum dots all have certain drawbacks. Comparing all these methods, the electrical depletion method has many advantages, such as electrical tunability by gate contacts, smooth confinement boundaries, good control and uniformity if the top gate patterns are uniform enough. Researchers have now, for the first time, applied the electrical depletion method to quantum wells and generate a large area of uniform quantum dots using a uniform metallic nanoholes array on top of quantum wells. This design for forming quantum dots has inherited all the advantages of the electrical depletion method. Furthermore, it can produce millions of uniform quantum dots easily, precisely, and controllably, which will help realize the wide applications of quantum dots in many areas.

SII NanoTechnology USA Inc. will be debuting a redesigned company website to assist current and potential customers in choosing the best X-ray detector and spectrometric systems for their companies.

Empa researchers have succeeded in growing sea-urchin shaped nanostructures from minute balls of polystyrene beads using a simple electrochemical process. The spines of the sea urchin consist of zinc oxide nanowires. The structured surface should help increasing the efficiency of photovoltaic devices.

Previous studies have revealed that single-walled carbon nanotubes (SWCNTs) strongly absorb light, especially in the near-infrared region, and convert it into heat. There even has been a report that fluffy SWCNTs can burst into flames when exposed to a camera flash, which means the local temperature has reached 600-700C. This effect has already been used to develop effective CNT-based cancer killers or extremely dark materials. In a new twist, researchers in China have now discovered that SWCNT buckypapers have a large Seebeck coefficient, indicating a strong capability to convert heat into electricity. Based on this, they have designed an opto-electronic power source which converts the incident light into electricity. While this has been discussed as a theoretical mechanism, the team at Tsinghua University in Beijing has actually fabricated an integrated device that outputs a macroscopic voltage, moving forward towards practical applications.

Researchers studying a gas of trapped ultracold atoms have identified a set of conditions, never before observed but in excellent agreement with new theoretical predictions, that determine the onset of a critical 'phase transition' in atomic arrays used to model the behavior of condensed-matter systems.
