Abstract
Samarium epitaxial crystalline layers have been grown by vapor deposition onto either tungsten field-electron emitters or a single macro-cyrstal, (011)-oriented tungsten low-energy-electron diffraction specimen. Optimum growth occurred for substrate temperatures in the range of 650 - 750 K. The epitaxial relationship most commonly observed was (0001)Sm // (011)W with [1120]Sm // [001]W. The surface lattice constant of Sm(0001) appears to be a few per cent larger than the bulk valueKeywords
