Graphene nanoribbon heterojunctions and heterostructures

Design of boron vacancy enhanced spin filtering graphene/BN zigzag nanoribbon heterojunctions

The spin-polarized electronic transport properties of zigzag graphene nanoribbons (ZGNRs) and boron nitride nanoribbons (ZBNNRs) heterojunctions with a boron vacancy are investigated by using nonequilibrium Green's function and density functional theory, especially under an external electric field. The model we used in this paper is chosen from the last essay we researched, the I–V curves in th...

Hierarchical graphene nanoribbon assemblies feature unique electronic and mechanical properties.

Graphene nanoribbons present intriguing electronic properties due to their characteristic size and edge shape, and have been suggested for a wide range of applications from electronics to electromechanical systems. To bridge the scales from their nanostructural geometry--the key for their unique properties--to the requirements critical for large-scale electronics and device applications, here w...

A graphene nanoribbon memory cell.

S D C1 C2 Over the past few years there has been a surge of interest in graphene, a recently isolated [ 1 ] one-atom-thick layer of carbon atoms arranged in a honeycomb lattice. From the application point of view this interest has mainly been driven by the high carrier mobility of graphene [ 2–4 ] which enables fabrication of fi eld-effect transistors (FETs) with much smaller channel resistance...

Half - metallic Armchair Graphene Nanoribbon

Submitted for the MAR10 Meeting of The American Physical Society Half-metallic Armchair Graphene Nanoribbon FUMIYUKI ISHII, KEISUKE SAWADA, MINEO SAITO, Kanazawa University — Among a variety of applications of graphenes, spintronics applications are considered to be hopeful. For an example, spin transport has been experimentally observed by using graphene layers [1]. There are two types of shap...
