IRGs

This seed project synthesizes and evaluates materials for potential use in molecular electronics. This work also uses synthesis to address how molecular structure can control electron transport and function. Focus is directed towards compounds that contain conjugated electron donating and electron withdrawing substituents in their molecular architecture. Appropriate installation of thiol or olefin linkers on […]

Photonic Building Blocks from Multiscale Materials
Our group is working to understand and control the optical properties of a novel class of radiative nanoparticles—fluorescent core-shell silica nanoparticles (C dots)—that combine the tunability of organic dyes with the durability of inorganic materials to achieve brightness levels comparable to quantum dots. The fundamental correlation between structure and photonic […]

The mission of IRG-1 is to develop new synthetic and theoretical methodology that will allow the design, synthesis, and study of functional macromolecules with unparalleled architectural control. These molecules will be assembled to create new materials and nanoscopic structures with the goal of understanding the relationships among structure, property, and function in novel hydrogels, nanotemplates […]

Fundamental Issues in Materials Integration on Silicon investigates the fundamental atomistic and mesoscopic mechanisms underlying the integration of materials, devices and structures on silicon, as an integration platform. Materials integration on Si leverages the power of CMOS through the addition of other components, thereby increasing function while maintaining the advantages and the versatility of […]

The next generation of polymer-based materials will rely on the incorporation of multiple components to achieve superior and tunable properties; this, in turn, will require control over chemical connectivity and morphology from the nanometer scale up to microns. The thermodynamic incompatibility of most polymer pairs demands a flexible strategy for designing hybrid materials in both […]

The last decade has witnessed considerable progress in the development of organic semiconductors as an alternative to amorphous silicon for low cost, thin film electronics. The attractive properties of organic semiconductors- low temperature processability, efficient electroluminescence, and reasonable charge carrier mobilities- have led to expectations of a new ‘plastic’ electronics with applications ranging from flexible […]

The unifying theme of the Magnetic Heterostructures group (IRG 3) is to achieve a thorough understanding of spin transport, magnetization dynamics, and exchange coupling in materials with precisely defined and well-characterized interfaces, including those with tailored interfacial disorder. Magnetism is the basis for many present, near term, and future technologies, including magnetic read heads and […]

Engineered nanoparticles present a wide range of opportunities for the synthesis and assembly of materials with entirely new electronic, optical or mechanical properties. They are of interest for materials science because their size-dependent characteristics give rise to an entirely new spectrum of materials properties. In addition, nanoparticles offer new ways of forming combinations of very […]

In IRG1, Chemically Advanced Nanolithography, we exploit self- and directed assembly and selective chemistry in combination with conventional and other nanolithography tools to push forward fabrication techniques of devices with dimensions on the order and larger than 10 nm. The two inter-related research themes of this IRG are molecular rulers and chemical patterning. The emphasis […]

The IRG research projects are augmented by seed projects in materials science research. At present there are three seed projects in the CCMR funded through a combination of NSF and Cornell University resources.

IRG2 seeks to understand the science, technology, and fabrication of large-scale ordered structures with features on the nanometer to micrometer scale. Substrates of square centimeters in area covered with trillions of organic or inorganic structures could be employed in nanofilters, sensors, catalytic supports, quantum dots, optical devices, and ultradense memories. Current foci of research include […]
