Abstract
The mechanism of conduction between a Ta/sub 2/O/sub 5/ film and a metal electrode was studied by means of photocurrent measurements. The nature of the metal/Ta/sub 2/O/sub 5/ interface is shown as well as the energy diagram deduced from the results. Transient current decaying with time has been observed in the Al/Ta/sub 2/O/sub 5/ interface and explained in terms of the space charge effect due to the blocking barrier of Al/sub 2/O/sub 3/ formed at the interface.<>
