Conductance quantization in graphene nanoribbons: Adiabatic approximation
A theory of electron states for graphene nanoribbons with a smoothly varying width is developed. It is demonstrated that the standard adiabatic approximation allowing to neglect the mixing of different standing waves is more restrictive for the massless Dirac fermions in graphene than for the conventional electron gas. In general, one can expect a well-pronounced conductance quantization only f...
متن کاملConductance in quantum wires by three quantum dots arrays
A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...

متن کاملQuantum transport in graphene nanoribbons patterned by metal masks
Graphene nanoribbons !GNRs" were fabricated by metal mask lithography and plasma etching. GNRs with width #20 nm show field-effect conductance modulation of #12 at room temperature and !106 at 4.2 K. Conductance quantization due to quantum confinement in low field transport was observed. Landauer formula was utilized to fit the experimental data and excellent agreement was obtained. The extract...
متن کاملQuantum dot behavior in bilayer graphene nanoribbons.
Bilayer graphene has recently earned great attention for its unique electronic properties and commendable use in electronic applications. Here, we report the observation of quantum dot (QD) behaviors in bilayer graphene nanoribbons (BL-GNRs). The periodic Coulomb oscillations indicate the formation of a single quantum dot within the BL-GNR because of the broad distribution function of the carri...
