The pre-patterning of a surface to obtain locally arranged nanostructures is usually done by complex patterning techniques like electron beam lithography, focused ion beam etching or ion implantation. These direct surface patterning techniques can cause crystal damage and defects degrading the quality and performance of the nanostructured elements. Other disadvantages are that these techniques only have short-range impact and are incompatible with batch processing.<br><br> <strong>Technology</strong><br> A method for fabricating layer assemblies with locally arranged nano-structures. A buried, selectively modified underlying layer is used to control the growth of nanostructures on the surface by controlling the laterally inhomogeneous strain distribution. This is done using standard lithography, etching and oxidation techniques. <br> <br>

A team of physicists from MPQ, Caltech, and ICFO proposes the combination of nano-photonics with ultracold atoms for simulating quantum many-body systems and creating new states of matter.
Ultracold atoms in the so-called optical lattices, that are generated by crosswise superposition of laser beams, have been proven to be one of the most...
According to new research out of the Texas A&M Health Science Center College of Medicine, that is indeed the case. Chetan Jinadatha, M.D., M.P.H., assistant...
Researchers from ICFO, MIT and UC Riverside have been able to develop a graphene-based photodetector capable of converting absorbed light into an electrical voltage at ultrafast timescales
The efficient conversion of light into electricity plays a crucial role in many technologies, ranging from cameras to solar cells.
Electrical charges not only move through wires, they also travel along lengths of DNA, the molecule of life. The property is known as charge transport.
In a new study appearing in the journal Nature Chemistry, authors, Limin Xiang, Julio Palma, Christopher Bruot and others at Arizona State University's...
