应用
Hafnium tert-butoxide [Hf(OtBu)4] is a mononuclear; volatile; and highly promising precursor for the deposition of HfO2 and other hafnium doped thin films by vapor deposition techniques. The deposited films show high dielectric constant suitable for semiconductor devices.

We demonstrate that the degree of branching of the alkyl (R) chain in a Hf(OR)4 precursor allows for control over the length of HfO2 nanocrystals grown by homocondensation of the metal alkoxide with a metal halide. An extended nonhydrolytic sol-gel
