| Outline of Annual Research Achievements |
Dr. Walen fabricated and analyzed single-layer insulating hexagonal boron nitride on nickel and copper surfaces using STM, LEED, and XPS. Single phthalocyanine molecules were adsorbed to the h-BN to determine the ability of the h-BN to optically and electronically isolate single molecules from the underlying metal substrate. It turned out that the h-BN was ineffectual for optical decoupling.
Thus, the experimental approach was changed, and Dr. Walen began analyzing transition metal dichalcogenide samples on many different substrates, prepared by our collaborators. We have been working closely with professors from these three universities to characterize many sample systems for her project.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The main purpose of Dr. Walen’s study is to better define model transition metal dichalcogenide devices, especially regarding their lateral defects and interfacial characteristics, at the single-atom level. We plan to achieve this using scanning tunneling microscopy, spectroscopy, and electroluminescence, all of which we can achieve with high spatial resolution. This study is crucial to understand the properties of specific defect and interfacial structures for further manipulation or fabrication.
|
| Strategy for Future Research Activity |
Dr. Walen will continue to analyze and characterize samples from our collaborators, investigating local physical, electronic, and optical properties at the single-atom level.
