ABSTRACT
This CAREER award is jointly funded by the Electronic and Photonic Materials Program (EPM) in the Division of Materials Research (DMR), and by the Electronics, Photonics, and Magnetic Devices Program (EPMD) in the Division of Electrical, Communications and Cyber Systems (ECCS).
Nontechnical description: New ideas continuously emerge to address fundamental and technological challenges at the intersection of materials science, nano-optics, condensed matter physics, and nanotechnology. Particularly exciting is to uncover new material systems, as well as controlled defects in solid materials, that support robust electronic resonances and can serve as the optically active medium for next-generation nano-optoelectronic devices. A transformative approach to controllable realization of defect-based quantum dots in atomically thin semiconductors is pursued in this project. The unique electronic properties of two-dimensional semiconductors enable a novel source of quantum light. The research activities present opportunity to introduce and engage high school, undergraduate and graduate students to research at the forefront of materials science and nano-optoelectronic device technology. The PI works closely with the University of Rochester Kearns Center - a center focused on increasing the number of low-income and historically underrepresented individuals pursuing undergraduate, graduate and professional education.
Technical description: The research component of this CAREER award explores a novel platform to realize semiconductor quantum dots, which are hosted in van der Waals heterostructures based on stacked two-dimensional atomically thin materials. Recent research shows that, in addition to supporting extended two-dimensional excitons, atomically thin semiconductors also exhibit quantum dot like defects that support localized, zero-dimensional excitons. The research objectives of this project are two-fold: (i) elucidation of the detailed electronic and fine structure of the two-dimensional-material quantum-dot excitons using state-of-the-art magneto-optical spectroscopy as well as time-resolved measurements of voltage controlled van der Waals heterostructures and (ii) incorporation of these defect-based quantum dots into photonic nanostructures to create a substrate for chip-based quantum information science and quantum metrology applications. The quantum dots in van der Waals heterostructures are expected to provide a novel platform for integrated solid-state quantum photonics, quantum information processing and quantum metrology as well as a rich condensed matter physics playground to explore the coupling of quantum dots and atomically thin semiconductors.

PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
The main objectives of this research program were three-fold. First, state-of-the-art magneto-optical spectroscopy as well as time resolved measurements of voltage controlled van der Waals heterostructures were employed to elucidate the detailed electronic and fine structure of the 2D-material quantum-dot-like excitons. Second, approaches to exciton control via electric field, magnetic field and strain made it possible to create the first spin-photon interface - desirable for quantum communication and quantum networks ? with optically active quantum defects in a van der Waal heterostructure. Third, underrepresented minority high school and undergraduate students were introduced to the excitement of quantum science both through research experiences in the PI?s lab as well as an immersive weeklong summer program called Photon Camp the PI directs.
Intellectual merit outcomes: Working with van der Waals materials we demonstrated the coherent optical control of defect excitons, how heterostructures could be assembled employing bandstructure engineering principles to reproducibly create a spin-photon interface and we have begun to understand the role Moire superlattices have on the photophysics of quantum emitters. Unique sample assembly techniques and experimental infrastructure was created to enable the new scientific discoveries. Quantifying the photophysical properties of quantum emitters in the diversity of 2D material heterostructure landscapes will inform future quantum technology devices based on this material platform.
Broader impacts outcomes: The broader impacts had both a training and broadening participation dimension as well as scientific impacts outside of the specific research domain. As a result of the CAREER award the PIs research group has trained 4 high school student interns, 1 high school teacher, 3 graduate students and 5 undergraduate students to varying degrees in quantum science. Additionally, nearly 100 high school students have been introduced to the excitement of quantum science and technology via the PI's Photon Camp. The scientific broader impacts have been the creation and demonstration of van der Waals materials that could support future quantum communication and quantum sensing initiatives.
