TL;DR: A slower hot-carrier cooling for C-excitons, in comparison with band-edge excitons is reported, and it is deduced that this effect arises from the favourable band alignment and transient excited-state Coulomb environment, rather than solely on quantum confinement in two-dimension systems.

Direct laser fabrication of large-area and patterned graphene at room temperature
TL;DR: In this article, a direct fabrication of graphene on solid carbon coated nickel surface was realized by laser irradiation at room temperature, where arbitrary patterns designed by computer aided design software were fabricated directly on Ni substrates without additional mask or setup.

Single-step synthesis of graphene quantum dots by femtosecond laser ablation of graphene oxide dispersions
TL;DR: Femtosecond laser ablation of graphene oxide (GO) dispersions could be employed as a facile and environmentally friendly synthesis method for GQDs, and can be employed in printing electronic devices by either printing patterns that are more conductive and/or reducing costs of the ink by decreasing the concentration of silver nanoparticles in the ink.

Production, properties and potential of graphene
TL;DR: In this paper, the most promising and appealing properties of graphene are summarized from an exponentially growing literature, with a particular attention to matching production methods to characteristics and to applications, including the high carrier mobility value in suspended and annealed samples for electronic devices, the thickness-dependent optical transparency and, in the mechanical section, the high robustness and full integration of graphene in sensing device applications, emphasizing on the high potential of graphene not only as a post-silicon materials for CMOS device application but more ambitiously as a platform for post-CMOS molecular architecture in
