World record in silicon integrated nanophotonics

Researchers achieved a new world record in the energy efficient integration in silicon. They optimized aperiodic grating couplers in the nanometer range with a new developed backside metal mirror. Through this new method a record coupling efficiency of 87 percent between optical fibers and photonic integrated waveguides on silicon wafers has been achieved.

Toward tinier transistors with germanium

The foundation of many, many modern electronic devices - including computers, smart phones, and televisions - is the silicon transistor. However, the shrinking of consumer electronics is driving researchers to investigate materials that can yield thinner transistors. Researchers have used x-rays to probe the electronic behavior of a germanium-based transistor structure, yielding important information that will guide future studies of how to make transistors smaller.

Nanotweezers allow precision control of enzymes

Researchers describe a pair of tweezers shrunk down to an astonishingly tiny scale. The group demonstrated that the nanotweezers, fabricated by means of the base-pairing properties of DNA, could be used to keep biological molecules spatially separated or to bring them together as chemical reactants, depending on the open or closed state of the tweezers.

New method to generate Laughlin states with atomic systems

In 1998, the Nobel Prize in Physics was conferred to the discovery of a new type of quantum fluid with fractional charge excitations, known as Laughlin state. Now, theoretical research proposes a method to generate this kind of states in two-dimensional systems of ultracold atoms, with possible applications in quantum computer.
