Figure 5a, b, c and 5d, e, f shows successive SEM images with increasing film thickness (decreasing transmittance) for Ag NW 1# and 3# (see "Materials and experimental method" section), respectively.
( dot{Q}_{c} ) is the convective heat loss, which is given by A s h(T 1 – T 2 ), in which A s is the superficial area of NW, 1 < h<10 is the convective heat transfer coefficient of air [27], T1 and T2 are the NW surface temperature and near-surface air temperature, respectively.
When the bottom bilayer of NW 1 reaches the periphery of NW 2, the As atoms in the bottom bilayer of NW 1 is not in lateral registry with that of NW 2. In principle now two scenarios compete with each other.
The stacking sequences of 2H can also equivalently be described as ···BCBCBC···, ···ACACAC···, etc. Suppose the first 2H structured NW (NW 1) retains the stacking order as ···ABABAB··· and the second 2H structured NW (NW 2) retains the stacking order as ···BABABA···.
The likelihood function is expressed as λ = nw μw nw 1 n G - nw n G - μw n G - nw if nw μw > n G - nw n G - μw otherwise This function detects the zone that is most likely to be a cluster.
