A process combining some comparatively cheap materials and the same antifreeze that keeps an automobile radiator from freezing in cold weather may be the key to making solar cells that cost less and avoid toxic compounds, while further expanding the use of solar energy.
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.
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.
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.
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.
Nikon has partnered with SUNY's College of Nanoscale Science and Engineering (CNSE) in a $350 million investment to develop the first of its kind next generation lithography technology on 450mm wafer and create 100 high-tech jobs.
The behaviour of a few particles can have important ramifications for how a system of many particles behaves. In particular, bound states of two, three or more particles can determine how particles will cluster, i.e. how particles are correlated, in a gas or fluid.
Imec has developed a Manganese (Mn)-based self-formed barrier (SFB) process that significantly improves Resistance Capacitance (RC) performance, via resistance and reliability in advanced interconnects. It provides excellent adhesion, film conformality, intrinsic barrier property and reduced line resistance. This technology paves the way towards interconnect Cu metallization into the 7nm node and beyond.
