We have developed a cryogenic pulsed laser deposition (PLD) system to deposit lithium films onto a quartz crystal microbalance (QCM) at 4 K. Adsorption isotherms of 4He on lithium were measured in the temperature range between 1.42 K and 2.5 K. The i

We have constructed a sliding block cryotribometer designed to measure friction at cryogenic temperatures and UHV conditions. An optical cryostat and high speed video was used to monitor the motion of the block. The temperature range of the measureme

We have developed a modulated null ellipsometer with sub-monolayer resolution to measure adsorbed liquid helium thin films at temperatures below 4 K. Adsorption isotherms of 4 He on gold, cesium, and graphite are presented. For Au and Cs substrates,

A cryogenic ellipsometer capable of measuring submonolayers of liquid helium has been developed. Methods for controlling drift and noise created by the cryostat windows and ellipsometer optics are discussed in detail. The cryostat vacuum windows were

We present high resolution and high speed (5 μs) photographs of 4 He drops undergoing pinch-off and sliding down a cesiated inclined plane. When a fluid drop is stretched and pulled apart by gravity, a balance of surface tension and inertia results

We have studied heterogeneous nucleation of liquid 4He on cesiated surfaces using calorimetric techniques. Nucleation kinetics are strongly influenced by wetting properties. Since liquid 4He does not wet cesium below 2K, substantial supercooling of t

The adsorption of a binary liquid mixtures onto a weakly attractive substrate has been studied in the vicinity of bulk liquid phase separation. A wetting transition between two different kinds of wetting films has been found. Below the wetting transi

Quartz-crystal microbalance isotherms of ${}^{4}\mathrm{He}$ on rubidium are presented. The isotherms are used to locate the prewetting transition and the onset of superfluidity in the adsorbed helium films. The phase diagram of He on Rb is distinctl

The quartz microbalance technique has been used to study the coverage of argon and methane films in the vicinity of the bulk triple point. In contrast to previous measurements, close to the triple point, the discontinuities in the coverage indicate f

The recent discovery that 4 He does not wet the surface of cesium makes possible the study of superfluid droplets. We have used a long focal length microscope to study superfluid 4 He droplets on a cesium surface. We find that 4 He droplets do not fl
