The controllable fabrication of self-scrolling SiGe/Si/Cr helical nanoribbons on Si(111) substrates is investigated. The initial lateral etching profile of the Si(111) substrates shows a 2-fold rotational symmetry using 4% ammonia solution, which provides guidance for initial scrolling of one-end-fixed nanoribbons

We demonstrate strong-to-perfect absorption across a wide range of mid-infrared wavelengths (5-12µm) using a two-layer system consisting of heavily-doped silicon and a thin high-index germanium dielectric layer. We demonstrate spectral control of the absorption resonance by varying the thickness of

The magnetic properties, electronic band structure and Fermi surfaces of the hexagonal Cr(2)GeC system have been studied by means of both generalized gradient approximation (GGA) and the +U corrected method (GGA + U). The effective U value has been computed within the

In this study, Zn2GeO4 hollow spheres were successfully fabricated by a template-engaged approach using zinc hydroxide carbonate (Zn4CO3(OH)6·H2O, ZHC) spheres as the template. During the hydrothermal process, Zn(2+) dissolved from the surface of the ZHC spheres could rapidly react with

In this paper we investigate the influence of n-type doping in Ge light emitting diodes on Si substrates on the room temperature emission spectrum. The layer structures are grown with a special low temperature molecular beam epitaxy process resulting in

Technologies are an integral part of our lives and we rely on them for such things as communication, heating and cooling, transportation, and construction. Improvements to technologies have made what they do for us more precise, automated, efficient, and powerful.

The price of tellurium, a key component in many thermoelectric materials, has risen in recent years, leading to the search for more cost-effective substitutes. This article presents silicide materials as a cheaper potential alternative.

In recent years, the price of tellurium, a key component in the bestperforming thermoelectric materials, has increased significantly, leading to the question, “Is it economically viable to produce thermoelectric generators on an industrial scale?

The unique properties of the rare-earth elements and their alloys have brought them from relative obscurity to high profile use in common hightech applications.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
