Adding a Dimension to the Infrared Spectra of Interfaces using Heterodyne Detected 2D Sum-Frequency Generation (HD 2D SFG) Spectroscopy

In the last ten years, two-dimensional infrared spectroscopy has become an important technique for studying molecular structures and dynamics.

New Dual Beam Focused Ion Beam System

Objective: To develop nanofabrication capabilities that will allow for writing structures as small as ~10 nm.

Approach: Use MRSEC funds provided by the State of Utah to purchase state-of-the-art nanofabrication capabilities to expand existing materials research capabilities.

Silicon Integrated High Speed Electrooptic Modulators

On-chip optical modulation is one of the most important functionalities for integrated silicon photonic circuits. We demonstrate that sputter-deposited polycrystalline metallic thin films are promising materials for realizing ultra-low power modulators.

CRISP NanoDays and Yale Pathways

On March 22, 2012, CRISP, in collaboration with Yale's Science Pathways, hosted a public lecture in support of the 2012 NanoDays national outreach campaign. IRG2 leader Jan Schroers gave a talk entitled, Strong as Steel, but Pliable as Plastic: Metals Conquering the Nanoworld. Hands-on demonstrations for students were provided by CRISP researchers.


Silane Passivation of Si Quantum dots


Colloidal silicon quantum dot solution is stable over months

Size Dependence of Multi-Exciton Generation

First principles modeling demonstrates  that the efficiency of Multi-Exciton Generation (MEG) increases as quantum dot size decreases resolving a major controversy.  The results were highly visible. 

Mechanical pressure can be used to resuscitate the beating “heart” of a polymer gel

Polymer gels undergoing a self-oscillating chemical reaction have been previously shown to pulsate autonomously while exhibiting periodic color changes. Van Vliet and Balazs have now demonstrated that a non-oscillating, quiescent gel can be “resuscitated” by applying mechanical pressure to the material. By varying the conditions of the reaction, the amplitude and
