Synthesis of Novel 2D and Quantum Materials
Our group specializes in the synthesis of novel quantum materials and two-dimensional (2D) using Chemical Vapor Deposition (CVD) techniques. By precisely controlling the vapor-phase transport of distinct precursors and optimizing the reaction kinetics within a tube furnace, we are able to grow high-quality crystals and atomic layers with tailorable properties. This versatile technique enables the formation of diverse material classes, such as topological insulators, 2D ferromagnets, and emergent altermagnetic materials.
Exploring Metastable Phases
This research thrust is about accessing metastable material phases to explore their extraordinary properties. To isolate these elusive, non-equilibrium states, we leverage a parallel set of structural and thermodynamic techniques. We can stabilize specific phases through precise epitaxial growth on substrates with particular cyrstal structures, manipulate the lattice using substrate-induced strain, alter phase boundaries with vertical pressure, or utilize fast cooling to kinetically trap transient atomic arrangements. Treating these techniques as a versatile array of tools allows us to systematically unlock and harness the novel quantum phenomena that emerge within metastable materials.
Property Modulation through Heterogeneities
Our group uses defect and dopant engineering to tailor the properties of two-dimensional and quantum materials. By intentionally introducing vacancies, substitutional dopants, interstitial atoms, and defect clusters, we can modify the local atomic structure and tune electronic bands, carrier transport, optical response, and magnetic order. This approach provides a powerful pathway to create materials with customized quantum functionalities, enabling new opportunities in nanoelectronics, optoelectronics, spintronics, and quantum information technologies.
