水是无处不在的，由于冰的重要性，冰的表面性质已经被研究了一段时间。已知在冰面上熔点以下存在类液态层(LLL)。我们使用表面热起伏光谱来研究微层厚度，包括它的厚度，对于纯冰和含有杂质的冰。我们发现，微透镜的性质在实验上与液态水的性质相同，厚度比以前的结果小得多。我们还发现，杂质会导致LLL更厚，并且非常不均匀，其性质取决于掺杂剂。
Water is ubiquitous, and the surface properties of ice have been studied for some time, due to their importance. A liquidlike layer (LLL) is known to exist on ice, below the melting point. We use surface thermal fluctuation spectroscopy to study the LLL, including its thickness, for pure ice, and for ice with impurities. We find that the properties of the LLL are experimentally those of liquid water, with thickness much smaller than previous results. We also find that impurities cause the LLL to be thicker, and quite inhomogeneous, with properties depending on the dopant.
