Low‐temperature deposition of zirconium and hafnium boride

Conductive (150 μΩ cm), adherent films of zirconium and hafnium borides have been deposited on various substrates by the low‐temperature (100–270 C) thermal decomposition of Zr[BH 4] 4 and Hf[BH 4] 4. Auger electron spectroscopy of these films shows that their composition is ZrB 2 and HfB 2.The film surfaces are oxidized and slightly carbon contaminated.
