Conformal Deposition of Conductive Single-Crystalline Cobalt Silicide Layer on Si Wafer via a Molecular Approach
(2018)The realization of metal-semiconductor contacts plays a significant role in ultrascaled integrated circuits. Here, we establish a low-temperature molecular approach for the conformal deposition of a 20 nm Co-rich layer on ... -
Design of periodic nano- and macro-scale textures for high-performance thin-film multi-junction solar cells
(2016)Surface textures in thin-film silicon multi-junction solar cells play an important role in gaining the photocurrent of the devices. In this paper, a design of the textures is carried out for the case of amorphous ... -
Development of a Sol-Gel Based Nanoporous Unsteady Pressure Sensitive Paint and Validation in the Large Transonic Onera S2MA Windtunnel
(2015)A new unsteady Pressure Sensitive Paint based on a nanostructured sol-gel coating has been developped and tested on a steel model of a civil aircraft in the ONERA's S2MA transonic windtunnel. Two inserts were fitted in the ... -
Grafted-to polymeric layers for highly adhesive electroless metal coatings on ultra-smooth 3D printed surfaces
(2022-03-24)A process has been developed to produce highly adhesive metallic layers onto polymeric surfaces. It is specifically aimed at ultra-smooth polymeric substrates produced by stereolithography (SLA) with applications in the ... -
