Effect of substrate temperature on the plasma texturing process of c‐Si wafers for black silicon solar cells

25.04.2016 | D. Murias, M. Moreno, C. Reyes‐Betanzo, A. Torres, P. Rosales, J. Martínez, R. Ambrosio, P. Roca i Cabarrocas, N. Ca ..., physica status solidi (a), 2016

We report on a study of the effect of the substrate temperature on the formation of black silicon on c‐Si wafers and consequently on the reduction of the wafer surface diffuse reflectance. We observed that lower substrate temperatures enhance the texturing processes producing completely black ...

[Report] Light-driven dinitrogen reduction catalyzed by a CdS:nitrogenase MoFe protein biohybrid

22.04.2016 | Katherine A. Brown; Derek F. Harris; Molly B. Wilker; Andrew Rasmussen; Nimesh Khadka; Hayden Hamby; Stephen Keable; ..., Science , 2016

The splitting of dinitrogen (N2) and reduction to ammonia (NH3) is a kinetically complex and energetically challenging multistep reaction. In the Haber-Bosch process, N2 reduction is accomplished at high temperature and pressure, whereas N2 fixation by the enzyme nitrogenase occurs under ambient ...

Effects of Thermal Electronic Excitations on the Diffusion of Oxygen Adatoms on Graphene

20.04.2016 | Tao Sun; Xinxin Yao; Stefano Fabris, Journal of Physical Chemistry A, 2016

We conduct first-principles calculations to study oxygen diffusion on the graphene surface as a function of temperature up to 3000 K. The minimum energy migration path and the corresponding activation energy are determined by the nudged elastic band method with explicit inclusion of thermal ...
