[求助] 求翻译 如下段落 (Google 的不要)

The desired diffusion of excitons towards the organic–organic
interface (process 2) poses stringent requirements on the
thin-film morphology. Exciton diffusion lengths in polymeric
and disordered molecular solids are typically in the range of a
few nanometers or a few tens of nanometers, and increase to
a few hundred nanometers for highly ordered crystalline samples.Consequently, the average spacing of organic heterojunctions
should be on the length scale of the exciton diffusion
lengths. This leads to a laterally structured architecture
with vertically interdigitated separate phases, as shown schematically
in Figure 10b, where every generated exciton should
be able to diffuse towards an organic–organic interface. In reality,
the fabrication of such ideal structures is inherently difficult
with both small-molecular and polymeric materials, in particular
because of the small length scales involved.

尝试如下:
期望的朝向有机 - 有机界面的激子扩散(过程2)对薄膜形态提出了严格的要求。在聚合物和无序分子固体间的激子扩散长度通常是在几纳米或几十纳米的范围内,高度有序的结晶样品则增加至几百纳米。因此,有机异质结的平均间距应该是在激子扩散长度的范围内。这会导致横向排列的结构与垂直排列的结构叉指式的分开,如图10b所示,每一个生成的激子应该可以朝有机 - 有机界面扩散。事实上,用小分子和聚合物材料制造这样的理想结构本质上是困难的,尤其是小尺度的原因。
