Program Highlights for year 2010
The goal of CRISP professional development workshops is to improve the quality and diversity of STEM education for science teachers in neighboring urban school districts. CRISP offers inquiry-based workshops which utilize CRISP specialized research facilities to emphasize the interdisciplinary nature of materials science and nanotechnology.
The unique properties of transition metal oxides allow electrons to be manipulated in new ways. At CRISP, we have created an oxide device that enables a gas of electrons to be expanded or compressed with an applied electric field. The expansion or compression of the gas modulates the speed of moving electrons.
Many species of birds have feathers with colors that are the result
of light scattering from a disordered arrangement of nanoscale air
spheres. The feathers appear to be the same color from every angle.
Inspired by these beautiful feathers, we design structures of polymer
nanoparticles that produce color the same way. This is a new way to make
A multi-partner collaborative effort has focused on understanding semiconductor-oxide interfaces. This involves atomic layer precision in synthesis of the structures, correlating the structure and electronic properties using first principles, and obtaining subatomic resolution of structures from synchrotron x-ray diffraction a the Advanced Photon Source (Argonne National Laboratory) and electr
Transition metal oxides exhibit many properties that can be harnessed in novel devices. For example, an epitaxial ferroelectric on silicon enables a nonvolatile transistor that remembers its state without continuous power consumption. A critical question is how the oxide/silicon interface affects the oxide functionality.
The vivid, angle-dependent structural colors of some butterfly wing-scales are produced by light scattering from complex three-dimensional nanoscale structures.
Molecular
semiconductors are important materials for technology applications, such as
solar cells. Current research focuses on how to organize molecules at interfaces for more efficient energy
conversion. Maryland MRSEC researchers
Nearly 500 K-12 students from NYC schools visited NYU MRSEC laboratories for science demonstrations as part of the MRSEC Scientific Frontiers Program
Developed class modules for 70 9th graders in the Urban Assembly Institute for Math and Science for Young Women, an all-girls school in Brooklyn for the underrepresented and underprivileged
Whispering Gallery Mode Carousel: Forces exerted by an evanescent light wave at the surface of a spherical glass resonator draw microscopic colloidal particles toward the resonator surface
Intensity of the red-shifted light provides an exponentially sensitive probe of the particle-resonator separation; wavelength probes the strength of the light-matter interaction
In high speed devices, electrons are accelerated to high energy by a high electric field; to understand device performance, it is important to know how those “hot” electrons relax by scattering with each other and with the environment (the graphene lattice and the SiC substrate).
