Stacking-dependent band gap and quantum transport in trilayer graphene
Graphene1–3 is an extraordinary two-dimensional (2D) system with chiral charge carriers and fascinating electronic, mechanical and thermal properties4,5. In multilayer graphene6,7, stacking order provides an important yet rarely explored degree of freedom for tuning its electronic properties8. For instance, Bernal-stacked trilayer graphene (B-TLG) is semi-metallic with a tunable band overlap, a...
متن کاملObservation of an electrically tunable band gap in trilayer graphene
A striking feature of bilayer graphene is the induction of a significant band gap in the electronic states by the application of a perpendicular electric field1–7. Thicker graphene layers are also highly attractive materials. The ability to produce a band gap in these systems is of great fundamental and practical interest. Both experimental8 and theoretical9–16 investigations of graphene trilay...
متن کاملObservation of Stacking Fault Tetrahedral in TWIP Steel
Low stacking fault energy face centered cubic (FCC) materials contain characteristic defect structures. Stacking fault tetrahedral are one of those rare structures that occur under special experimental conditions. For the first time, stacking fault tetrahedral were observed in Fe-30Mn-3Al-3Si twinning induced plasticity (TWIP) steel. Their presence resulted from a quenching heat treatment.
متن کاملElectric field control of soliton motion and stacking in trilayer graphene.
The crystal structure of a material plays an important role in determining its electronic properties. Changing from one crystal structure to another involves a phase transition that is usually controlled by a state variable such as temperature or pressure. In the case of trilayer graphene, there are two common stacking configurations (Bernal and rhombohedral) that exhibit very different electro...
متن کاملMolecular adsorption induces the transformation of rhombohedral- to Bernal-stacking order in trilayer graphene.
The Bernal (ABA)-stacked graphene trilayer is presumed to be thermodynamically more stable than the rhombohedral (ABC) counterpart. However, the thermal transformation from ABC to ABA domains does not occur at a temperature lower than 1,000 °C. Here we report that ABC-stacked trilayers are transformed to ABA-stacked layers after an organic molecule triazine is evaporated onto graphene surfaces ...
