Journal ArticleDOI
On the mechanisms of precipitation of graphene on nickel thin films
Laurent Baraton,Zhanbing He,Chang-Seok Lee,Costel Sorin Cojocaru,Marc Châtelet,Jean-Luc Maurice,Young Hee Lee,Didier Pribat +7 more
TL;DR: In this paper, the authors used transmission electron microscopy to analyse the precipitation process in detail, which appears to imply carbon diffusion over large distances and at least two distinct microscopic mechanisms.

Journal ArticleDOI
Density control of electrodeposited Ni nanoparticles/nanowires inside porous anodic alumina templates by an exponential anodization voltage decrease
B. Marquardt,Laurent Eude,M. Gowtham,G Cho,H J Jeong,Marc Châtelet,Costel Sorin Cojocaru,B.S. Kim,Didier Pribat +8 more
TL;DR: Combined with the ability to vary the pore diameter and repetition step over ∼2 orders of magnitude (by varying the anodization voltage and electrolyte type), the control of the pORE filling percentage with metal particles/nanowires could bring novel approaches for the organization of nano-objects.
Journal ArticleDOI
Cup‐Stacked Carbon Nanotube Schottky Diodes for Photovoltaics and Photodetectors
TL;DR: High performance optoelectronic devices based on cup-stacked carbon nanotubes are realized and furthermore tuned by using nanotube’s defective surface as effective decoration sites transforming nanot tubes resistors into Schottky diodes.
Journal ArticleDOI
Synthesis of conducting transparent few-layer graphene directly on glass at 450 °C.
Chang-Seok Lee,Costel Sorin Cojocaru,Waleed Moujahid,Bérengère Lebental,Marc Chaigneau,Marc Châtelet,François Le Normand,Jean-Luc Maurice +7 more
TL;DR: This work demonstrates the large-area formation of continuous transparent graphene layers at temperatures as low as 450 °C using a plasma-enhanced chemical vapour deposition process, and measures the optical transmittance of the layers without any transfer.
