THRUST 1: RECONFIGURABLE SOFT MATERIALS
The core principle of Thrust 1 is a templated self-assembly of macromolecular and nanocomposite systems that can lead to differential equilibrium states. The assembly components of Thrust 1 rely on reversible covalent bonding and non-covalent interactions (nucleic acid base pairing, ionic bonding, hydrophobic interactions, 𝜋-stacking) to form organized structures. We propose to use photothermal effects, photoisomerization, redox chemistry and remodeling nucleic acids as driving forces for transformation between different equilibrium assemblies.
THRUST 2: CONTROL OF NANOSTRUCTURE FOR ENERGY AND ELECTRONICS
Thrust 2 projects use new, unconventional approaches to synthesize solid-state nanostructures with novel structures or on non-traditional substrates. We will produce transition metal dichalcogenides by laser-induced heating, epitaxial oxides on silicon by molecular beam epitaxy, and nanostructured mixed metal oxides using chemical and aerogel synthetic routes. We will also design interface arrangements and growth conditions for growth of III-V semiconductors on Si using predictive modeling. Unique material properties such as defects due to the out-of-equilibrium and hybrid source growth techniques will be utilized for catalysis, energy storage, photoelectrochemical performance in solar-driven water reduction and nanoelectronic devices for resistive switching and active photonics (lasers, amplifiers) on Si.
