- Title
Mesoscopic fast ion conduction in nanometre-scale planar heterostructures.
- Authors
Sata, N.; Eberman, K.; Eberl, K.; Maier, J.
- Abstract
Reports the preparation, by molecular-beam epitaxy, of defined hetero-layered films composed of CaF[sub2] and BaF[sub2] that exhibit ionic conductivity (parallel to the interfaces) increasing proportionally with interface density. Agreement of the results with semi-infinite space-charge calculations; Observation of the predicted mesoscopic size effect; Insight into ionic contact processes which the study provides; Application for the development of ionic conductors of potential relevance for medium-temperature applications.
