We report on a new route to grow epitaxial copper (cu) ultra thin films (up to 150 nm thick) at ambient temperature on si(001) wafers covered with native oxide without any prior chemical etching.

By using phenylacetylene as the precursor, here we successfully achieved the selective synthesis of the tetraphenyl[4]radialenes on cu(100) surfaces. the tetramerized products were visualized by. This study investigates the warpage and stress relaxation of a transferred gan epi layer on electroplated cu substrates. varying the electroplating current density makes it possible to manipulate the crystallographic structure and hardness of the electroplated cu substrate. a harder electroplated cu substrate (with the (111) preferorientation) has less warpage and more stress relaxation in the.

Here, we propose a facile solution immersion method of fabricating interdigitated copper electrodes with an in situ converted array of cu(oh) 2 @feooh nanotubes (nts). a copper current collector can be patterned together with widely employed copper circuits by a facile copper patterning approach based on cost effective electroless catalytic. Conversion of carbon dioxide (co 2) into valuable chemicals, especially liquid fuels, through electrochemical reduction driven by sustainable energy sources, is a promising way to get rid of dependence on fossil fuels, wherein developing of highly efficient catalyst is still of paramount importance.
