It is shown that the evaporation procedure has a significant influence in the superconducting transition temperature of freshly deposited beryllium films. The maximum value, T/sub c/ = 9.75 /sup 0/K, is observed for beryllium films (thickness approx.400 A) obtained from the melt. It is shown that T/sub c/ increases smoothly as the film thickness increases for all one-step evaporation techniques. The curve T/sub c/(d) is higher for higher temperatures of the beryllium supply. The superconducting form of beryllium is retained for large thicknesses if the films are formed under strictly controlled conditions.
