IRGs

IRG1 investigates how magnetism affects electron transport in a broad class of novel materials with unusual magnetic states. The presence of strong interaction between electrons leads to a variety of magnetically ordered states ranging from ferromagnetism, ferrimagnetism, antiferromagnetism, spin density waves, and the spin-Peierls state. Strong interest in how magnetism affects charge transport has come […]

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 […]

Many state-of-the-art microelectronic, photonic and MEMS devices are based upon small scale contacts for which performance and fabrication are governed by the deformation, adhesion, and transport properties of many diverse materials and interfaces. Yet despite the widespread use of such devices, there is only a limited understanding of the phenomena governing adhesion, a shortfall that […]
