利用微分吸附技术结合声学方法，研究了加压液相中固体He 4在石墨箔上的分层生长。在低压下，我们发现一阶相变每次完成一层，而在高压下的过渡发生在中层附近，在石墨上的外延相的覆盖特性。我们的研究结果支持最近的多层膜生长理论的预测。
With use of a differential adsorption technique combined with acoustics, we have investigated the layered growth of solid He 4 on Grafoil from the pressurized liquid phase. At low pressures, we found a first-order phase transition each time a layer was completed, whereas at high pressures the transitions occurred near midlayer, at a coverage characteristic of an epitaxial phase of He on graphite. Our results support the predictions of recent theories of multilayer growth.
