graphene:石墨烯,单层碳原子材料wrinkle:褶皱curvature:曲率,弯曲程度flexoelectricity:挠曲电性,不均匀弯曲产生电荷的现象probe:探针Raman spectroscopy:拉曼光谱,一种用激光观察原子受拉伸或压缩情况的方法polarization:极化,材料内部正负电荷的分离nanoscale:纳米尺度的tune:调节,使性质达到需要的状态evidence:证据ultrathin:超薄的The strength of the effect depended more on how sharp a wrinkle was than on how tall it was.The strength depended more on one thing than another,意思是「效果强弱更多取决于一个因素,而不是另一个因素」。how sharp 和 how tall 都是宾语从句,分别表示「褶皱有多尖」和「褶皱有多高」。这里的比较重点是:尖锐程度比整体高度更关键。110.1002/adma.202518224。2 原论文可在 Advanced Materials 查看。This story was produced automatically by a channel.
