Spatially and Dimensionally Confined Structures and Assembly

The natural evolution of functional materials’ architecture calls for their confinement in spatial and dimensional modes. Here, spatial confinement refers to inevitable attachment of materials to a substrate or an overlayer(s), for example. Dimensional constraint arises from the ubiquitous need for materials to be confined to 0- (i.e., dots), 1- (lines) and 2- (i.e., films/membranes) dimensions to enhance aerial density and possible novel properties. Further, by juxtaposing two or more functional materials in close proximity, there are exciting new opportunities for synergistic coupling of disparate phenomena in hybrid confined materials systems.
Thus, our objectives span fundamental studies of spatial/dimensional confinement to harnessing their technological opportunities. We are particularly interested in functional oxides and emerging 2-D layered materials.
Embedded in these initiatives are varied nanopatterning approaches, in-situ and ex-situ characterization of nanopatterns, using photon (light, synchrotron), ion, scanning probe and electron microscopy.
