Abstract
The superconducting properties of bulk films(0.02- 0.06 mm thick) of Nb3 Ge deposited on Cu substrates by chemical vapor deposition have been studied along with physical parameters characterizing these deposits. Results of susceptibility measurements showing superconducting onsets greater than 21 K and resistivity measurements showing onset greater than 22 K are presented along with heat capacity measurements. Data are also presented defining a relationship between superconducting transition temperature and lattice spacing throughout the range of 4 - 21 K. In addition, the effects of substrate temperature and substrate material, as well as mechanical properties such as substrate adherence are described.
