相反,它们只能在表面的原子间跳来跳去。
Instead, they were merely shuffling between different atoms at the surface.
然而,研究人员并非采用加热整个样本的方案,而是使用了原子力显微镜(afm)一个加热探针去转换出一条仅有12纳米宽的导电带。
However, instead of heating the entire sample, the researchers used a hot atomic force microscope (AFM) tip to convert very narrow ribbons, measuring just 12 nm across, into reduced graphene.
原子力显微镜是运用一种微小的探针去“感受”样本表面,能得到高分辨率的影像(约5纳米的分辨率)。
Atomic force microscopy generates very high-resolution images (about 5-nanometer resolution) by “feeling” the surface of a sample with a tiny probe tip.
We are going to now go into the atom and try to understand the scientific basis for this observed behavior.
我们现在要讲讲原子,并试着去理解这个观察行为,的科学原理。
And what he said was that when you get down to atomic length scales there are limits, there are constraints on our ability to observe.
讲的就是,当你去进入到原子长度的尺度中,我们的观察能力,有一定的限制条件。
That's amazing, you can get atoms to smash atoms and create a chain reaction and create power-- that's a pretty amazing invention.
很惊人,你可以利用原子去做加速粒子,并产生连锁反应,然后创造能量-,那是个十分惊人的发明。
