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: Metaheuristic algorithms such as simulated annealing (SA) has been implemented for optimization in combinatorial problems, especially for discreet problems. SA employs a stochastic search, where high-energy transitions (“hill-climbing”) are allowed with a temperature-dependent probability to escape local optima.
Project Summary: Realization of wafer-scale single-crystal films of transition metal dichalcogenides (TMDs) such as WS2 requires epitaxial growth and coalescence of oriented domains to form a continuous monolayer.
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.
Project Summary: The sticking coefficients of thermally evaporated chalcogen elements selenium and tellurium were experimentally determined as a function of temperature. Their direct and quantitative determination provides important insights to comprehend and
Project Summary: The first ReaxFF force field developed for 2D-WSe2 provides the community with a highly efficient means that describe material growth, phase transitions, defect form
Project Summary: The interplay between topology in momentum space and topology in real space creates a vibrant playground for studying emergent phenomena in condensed matter physics. Topology in momentum space manifests in nontrivial band structures and is directly revealed by the quantum anomalous Hall effect (QAHE) observed in magnetically-doped topological insulators (TIs).
Project Summary: The intercalation of a molecule or ion in a layered structure is key to enhancing energy storage, material conductivity, intercalant structural ordering, and the formation of two-dimensional (2D) superconducting states. The process of intercalation modifies the vibrational energy of the host, which can be monitored non-invasively by Raman spectroscopy.
