  • Fast synthesis of large-area bilayer graphene film on Cu
  • Bilayer graphene (BLG) is intriguing for its unique properties and potential applications in electronics, photonics, and mechanics. However, the chemical vapor deposition synthesis of large-area high-quality bilayer graphene on Cu is suffering from a low growth rate and limited bilayer coverage. Herein, we demonstrate the fast synthesis of meter-sized bilayer graphene film on commercial polycrystalline Cu foils by introducing trace CO2during high-temperature growth. Continuous bilayer graphene w
  • Oxidization-temperature-triggered rapid preparation of large-area single-crystal Cu(111) foil
  • The controlled preparation of single-crystal Cu(111) is intensively investigatedowing to the superior properties of Cu(111) and its advantages in synthesizinghigh-quality 2D materials, especially graphene. However, the accessibility oflarge-area single-crystal Cu(111) is still hindered by time-consuming, compli-cated, and high-cost preparation methods. Here, the oxidization-temperature-triggered rapid preparation of large-area single-crystal Cu(111) in which anarea up to 320 cm2 is prepared with
  • Intrinsic wettability in pristine graphene
  • The wettability of graphene remains controversial owing to its high sensitivity to the surroundings, which is reflected by the wide range of reported water contact angle (WCA). Specifically, the surface contamination and underlying substrate would strongly alter the intrinsic wettability of graphene. Here, the intrinsic wettability of graphene is investigated by measuring WCA on suspended, superclean graphene membrane using environmental scanning electron microscope. An extremely low WCA with an
  • Clean transfer for high-intactness suspended large single-crystal graphene membranes and liquid cells
  • The atomically thin 2D nature of suspended graphene membranes holds promising in numerous technological applications. In particular, the outstanding transparency to electron beam endows graphene membranes great potential as a candidate for specimen support of transmission electron microscopy (TEM). However, major hurdles remain to be addressed to acquire an ultraclean, high-intactness, and defect-free suspended graphene membrane. Here, a polymer-free clean transfer of sub-centimeter-sized graphe
  • New growth frontier: superclean graphene
  • The last 10 years have witnessed significant progress in chemical vapor deposition (CVD) growth of graphene films. However, major hurdles remain in achieving the excellent quality and scalability of CVD graphene needed for industrial production and applications. Early efforts were mainly focused on increasing the single-crystalline domain size, large-area uniformity, growth rate, and controllability of layer thickness and on decreasing the defect concentrations. An important recent advance was t
