Abstract

Previous studies have revealed the possibility of observing prewetting phenomena of4He films on alkali substrates, particularly on Na where the prewetting jump was predicted to be the largest (5.25 layers). The well depth D has been calculated for Na to be 10 K. Given the various uncertainties in the calculation, we have explored a range of D values, from 10 to 15 K. Additionally, we study the interesting possibilities of a layered substrate, with Na preplated on top of metal substrates, such as Cu and Ne, on which the prewetting jump can be observed as a function of the Na thickness.
