Project Summary: An understanding of the surface chemistry of substrates used as support for 2D-chalcogenide growth is essential for controlling the synthesis of these materials. As such, we need computational methods that can be used to study the reaction dynamics of these support materials.
Project Summary: Contemporary approaches to non-volatile magnetic random access memory (MRAM) rely on using an electrical current (charge) to change the magnetization (spin) of a ferromagnetic material.
Project Summary: The performance of nanoscale metals in applications such as plasmonics, photodynamic therapy, and photocatalysis is influenced by their ability to absorb and transduce energy to their surroundings. In this study, we measured the non-equilibrium carrier dynamics in an air-stable 2-D polar metal heterostructures.
Project Summary: The two-dimensional semiconductors phosphorene and isoelectronic SnS have attracted extensive research interest for potential applications in optoelectronics, spintronics, catalysis, sensors, and energy conversion.
What Has Been Achieved:
Epitaxial WS2 monolayers on 2” diameter sapphire that exhibit a unidirectional alignment of domains resulting in coalesced films that are largely free of inversion domain boundaries.
Importance of the Achievement:
What Has Been Achieved:
We developed and validated a ReaxFF description for Ba/SrTiO3 perovskites.
Importance of the Achievement:
These ReaxFF parameters can be straightforwardly combined with existing ReaxFF descriptions for Mo/W/Se/S/C/O/H, enabling simulations of MoWSeS-material growth on STO support.
Unique Feature(s) of the MIP that Enabled this Achievement:
This work responds to a continuing external user interest in ReaxFF parameters for 2D materials and their growth substrates
What Has Been Achieved:
We carried out a careful study of the effect of 3 different capping layers on interfacial superconductivity in FeSe/SrTiO3 heterostructures.

What Has Been Achieved:
A new ReaxFF potential for large-scale simulations of structural engineering and synthesis of Two-dimensional WSe2 has been made available to the 2D community
Importance of the Achievement:
What Has Been Achieved:
We used MBE to Dirac semimetal/ferromagnet metal (Cd3As2/Ni0.8Fe0.2) heterostructures and measured spin-charge interconversion using spin pumping and spin torque ferromagnetic resonance. Importance of the Achievement: This work showed efficient spin-charge interconversion in a Dirac semimetal and revealed a surprising enhancement in the interconversion efficiency with an oxidized interface.
