Rapid growth of large area graphene on glass from olive oil by laser irradiation

Abstract: Although homogeneous, high quality graphene can be fabricated on a Cu or Ni sheet using the traditional chemical vapour deposition method at high temperatures (over 1000 °C) under specific atmospheric conditions, their transfer to another substrate is difficult. In this paper a novel method of rapidly (i.e. 3–6 s of laser irradiation) producing a large area (>3 cm2) graphene film from olive oil on a glass surface (pre-coated with a 5–28 nm thick Ni film) with defocused, large area continuous laser irradiati… Show more

“…The above results prove that few-layered graphene is almost fully covered on the surface of the sample. The quality of as-grown graphene, as well as the morphology of the surface of quenched Si wafer, was similar to that of graphene synthesized by laser direct writing [ 18 ].…”

“…Another recently reported method, laser direct writing, has shown the potential to achieve large area or patterned graphene by the heating effect of laser. LinLi’s team at Manchester University used laser irradiation to directly produce a large area graphene film with a size of about 3 cm 2 in 3–6 s on a glass substrate pre-coated with a 5–28-nm-thick Ni film covered with olive oil [ 18 ]. However, a high-power laser source of 16 kW was required to give a laser spot of 60 mm with uniformly distributed energy.…”

“…Besides the CVD method, people are trying to develop other growth methods of graphene to meet the requirements to achieve real applications, including high efficiency, large sample size, and low cost, as well as the quality of graphene. The laser direct writing (LDW) ultrafast technique is one of the promising synthesis methods to produce graphene. , Lu et al . successfully obtained graphene patterns on insulating substrates by a femtosecond LDW process .…”

“…Most recently, Lin Li et al . generated a much larger laser spot with a uniform power distribution using a powerful laser source to produce a graphene film with a size of about 3 cm 2 in 3–6 s on a glass substrate . The above ultrafast methods apparently improved the production rate of graphene films.…”
