Grey/Myer 里有关于 mobility degredation 有这么一段话: A physical reason for (mobility degredation) is that increasing the vertical electric field forces the carriers in the channel closer to surface of the silicon, where surface imperfections impede their movement from source to drain. 这个 "surface imperfection" 怎么理解?.. 它和造成 1/f noise 是同一个 imperfection吗?..

恩, 你说的是对的.. 我又翻了一下 Razavi, 里面说, (this) leads to more carrier scattering and hence lower mobility. 不过不明白为什么 carrier scattering will become more severe at silicon surface.. 我想可能是因为 silicon surface 的 crystal lattice 有更多的 defects ... 不知道这样理解对不对..
