zigzag (ZZ) and armchair (AC) edgesscanning probe lithography (SPL)The atomic edge structure of graphene governs its unique electronic properties with applications in nanoscale electronics and optoelectronics. To fully realize its potential, it is critical to develop a precision etching process ...
There are two types of edges created; zigzag and armchair edges, when a graphene sheet is cut into fragments. The presence of edges importantly affects the electronic structure in graphene depending on the geometry of edges. At zigzag edges, nonbonding edge state is created, which is the origi...
In particular, we show that the tuning of spin extends to larger widths for the armchair GNRs than for the zigzag GNRs. Here we also report that the relaxation rate vanishes like L^5 L^5 .doi:10.1063/1.4923225Prabhakar, SanjayMelnik, Roderick...
The presence of structure-dependent edge states of graphite is revealed by both ambient- and ultra-highvacuum- (UHV) scanning tunneling microscopy (STM) / scanning tunneling spectroscopy (STS) observations. On a hydrogenated zigzag (armchair) edge, brigh
摘要 The edges of nanoscopic objects determine most of their properties. For this reason the edges of honeycomb carbon-always considered either zigzag- or armchairlike-need special attention. In this Brief Report we provide experimental evidence confirming a previous unexpected prediction: zigzag is a...
Joule heating is thus shown to provide an effective way to produce clean zigzag and armchair edges, which could be useful for both fundamental studies of edge reactivity, magnetism, and could provide a route for increasing carrier mobility and for the development of future electronics applications....
aIt is also expected that zigzag and armchair graphene edges will exhibit different electrochemical properties and, although fabrication of purely zigzag or armchair edges is difficult, a breakthrough in this area is expected. 它也预计之字形和扶手椅子graphene边缘在这个区域将陈列不同的电化学物产,虽然...
armchairzigzagreczagzz-57DFTStability of 3 types of graphene nanoribbons on Ru(0001) is studied with DFT. While the reczag edge is more stable in vacuo, the zigzag edge is more stable on Ru. The zigzag and armchair edges are almost isoenergetic on the Ru surface. The graphene edges ...
SiC nanoribbons have zigzag or armchair edges and a hexagonal honeycomb shape similar to other nitride-based nanoribbons [7]. These nanoribbons' margins SiC nanoribbons have great potential for gas molecule detection by utilizing these features [8, 9]. SiC nanostructures, for instance, have shown ...
