This can be for any year.
2DCC-Nanofab REU Site: Scalable Nanomanufacturing of Complex Materials
In the summer of 2022, the 2DCC hosted 10 undergraduate students through the Research Experience for Undergraduates (REU) Site titled “REU: Scalable Nanomanufacturing of Complex Materials,” all of which were onsite. The REU site is jointly organized by 2DCC and the Penn State Nanofabrication facility.
FlU/2DCC PREM: Innovations in Materials, Processes and Applications for Quantum Technologies (IMPAQT)
Florida International University (FIU)/2DCC PREM IMPAQT focuses on advancing the synthesis and processing of 2D materials and 2D layered chalcogenides for fundamental studies and applications in quantum communication and sensing. Specific highlights for 2022-2023 include:
Graphene and Beyond Workshop: 2022
The 2DCC completed its 6th year of sponsorship of the Graphene and Beyond Workshop in 2022. Including the virtual activity in 2021 due to the pandemic, the six workshops have included >1000 individuals from academia, government and industry across all career levels have attended. The 2DCC has broadened participation by sponsoring travel and registration for dozens of users and potential users particularly from MSI
STEP FORWARD
What Has Been Achieved:
A geospatial tool that enables users to identify minority-serving, primarily undergraduate, and non-R1 institutions in specific geographical areas, selecting for research activity in areas of interest, to enhance visibility and accessibility.
Importance of Achievement:
This tool is designed to broaden participation and strengthen trans-disciplinary community connections through travel extension and is also designed in a manner that can potentially serve additional use cases.
Tunneling Effects In Crossed Ta2Pt3Se8−Ta2Pd3Se8 Nanowire Junctions: Implications For Anisotropic Photodetectors
What Has Been Achieved:
This work successfully fabricated nano-scale crossed junctions composed of two vdW nanowires: p-type Ta2Pt3Se8 (TPtS) and n-type Ta2Pd3Se8 (TPdS) and revealed its unique electronic and optoelectronic properties.
Importance of the Achievement:
This work not only reveals a route to build a nanoscale crossed junction between two quasi-1D vdW materials, but also shed light on the electrical transport and photocurrent generation mechanisms for the nanoscale crossed junctions.
Data Curation And Discovery – Making Experiments And Discovery Remotely Accessible And Actionable
What Has Been Achieved:
2DCC’s web-based facility-wide data management system has captured the full history individual samples with over 5000 materials synthesis samples and over 6000 ex-situ characterizations (e.g., AFM, STM, TEM, XRD, XPS, among many others). This extensive and growing database forms the impetus for new, creative research through the data request mechanism whereas remote users can open new lines of experimental or data science inquiry through packaging of certain synthesis and/or characterization data.
Unveiling The Wafer Scale Perfection Of 2D Materials Using Azimuthal Reflection High-Energy Electron Diffraction Map
What Has Been Achieved:
We have demonstrated an efficient method to determine the symmetry and lattice constants as well as the long-range perfection of 2D materials using glancing incident electron diffraction.
Importance of the Achievement:
This ARHEED methodology can be applied to other epitaxial 2D materials and to examine the wafer scale structure and perfection.
Unique Feature(s) of the MIP that Enabled this Achievement:
Picosecond Laser Ultrasonic Measurements Of Interlayer Elastic Properties Of 2H-MoSe2 And 2H-WSe2
What Has Been Achieved:
Ultrafast optical pump-probe measurements of sound velocity, elastic constants, and phonon lifetimes in TMD crystals.
Importance of the Achievement: Phonon lifetime measurements for these novel materials are rare, and they are useful in predicting thermal conductivity. Also the strong reflectivity signals produce by these relatively small elastic strains are a promising indicator of the future effectiveness of these materials as transient ultrasonic strain sensors.
