((c) and (d)) Phonon dispersion relations and transmission functions of aGNR and its GNW counterpart.
Zhou et al., using first-principles-based NEGF simulations, investigated the TE properties of hetero-junctions between aGNRs and armchair GyNRs and found that phonon transport is substantially suppressed at the GNR-GyNR interfaces [171].
In this paper, we investigate a junction consisting of a single iron atom adsorbed on armchair hexagonal boron nitride nanoribbon (Fe@ABNNR) contacted with two semi-innite leads composed of nitrogen-doped AGNR (N-AGNR).
Examined systems consist of armchair hexagonal boron nitride nanoribbons (ABNNR) contacted with two semi- innite armchair graphene nanoribbon electrodes (AGNR).
There are two types of GNRs: Zigzag edge GNRs (ZGNRs), which are cut along the zigzag dimer chain, and armchair edge GNRs (AGNRs), which are cut along the direction perpendicular to the zigzag dimer chain [31].
It has been shown that AGNRs are more stable than ZGNRs.
The calculated band structures and density of states DOS of undoped and N-doped AGNRs leads, and the DOS of isolated region are shown in Fig.
A microscope glass slide with double sided tape was used to attach the AgNRs samples.
Figure 4 shows normalized electric field distribution of the 100K and 300 K AgNRs. The scale baron the right represents the normalized amplitude of the scattered electric field with respect to the incident electric field amplitude.
Based on the electric field enhancement observed in the 100 K grown AgNRs compared to the 300 K AgNRs, a parametric study was done by varying the spatial distances ([L.sub.x]) between the adjacent nanorods for the 100 K configuration.
The calculated enhancement factor for the 100 K grown AgNRs was [G.sub.sers] - 1.85 x [10.sup.6] and that of 300K grown AgNRs was [G.sub.sers] - 6.22 x [10.sup.5].
Figure 6 shows the SERS spectra collected from 100 K and 300 K AgNRs that were incubated with 4-ABT vapor for 5, 20, 30, and 60 minutes.
