Program Highlights for year 2010

CRISP Professional Development Workshops

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.

Creating new devices using oxide materials

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.

What does soft matter physics have to do with bird feathers?

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

CRISP – National Laboratory Collaborations: Advanced Photon Source & Brookhaven National Laboratory

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

Impact of interfacial bonding on oxide functionality

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.

What has soft matter physics got to do with butterfly colors?

The vivid, angle-dependent structural colors of some butterfly wing-scales are produced by light scattering from complex three-dimensional nanoscale structures.

Charge Transfer Across Oriented Molecular Interfaces

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

NYU MRSEC Highlight: Education and Outreach

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

NYU MRSEC Seed Highlight: A Photon Driven Nano-lander orbiting a Micro-moon

 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

Ultrafast Relaxation of Hot Dirac Fermions in Epitaxial Graphene

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).
