The main objective of this project was the experimental demonstration of the theoretically predicted enhanced quantum-mechanical tunneling through layered crested barriers. If demonstrated in silicon-compatible materials with sufficient endurance under electric stress, this effect may enable high-density, high-speed nonvolatile memories that may potentially replace DRAM as the main random access memories of semiconductor electronics. With that objective, we have combined the expertise at Stony Brook University in crested barrier theory Prof. Konstantin Likharev and aluminum oxide layer growth Prof. James Lukens, Dr. Vijay Patel with that of Yale University Prof. T.P. Ma, Dr. X. Wang in jet vapor deposition of silicon nitride and silicon dioxide films, as well as in nonvolatile memory technology.
