Nanostructured materials can enable novel and unusual electronic, electrochemical, and optoelectronic functionalities. However, to harness such properties in practical devices it is necessary to understand and characterize the dynamic of carrier relaxation that are either intrinsic to the material or are related to device interfaces or defects. The goal of the Pump and Probe Micro-Spectroscopy program in the Center for Nanoscale Science and Technology (CNST) is to develop measurement tools and methods to characterize and understand the carrier dynamics in materials and devices with high temporal, spectral and spatial resolution.

The CNST is building a new pump and probe microscope for enabling the acquisition of broadband, time-resolved reflection and transmission spectra with high spatial (≈ 1 µm) and temporal (few fs) with high throughput. High throughput is achieved using an array of detectors that enables parallel acquisition of pump-probe delay times, wavelength-resolved spectra, and spatial information. This novel technique will be applied to characterize advanced materials and devices in applications for photovoltaics, plasmonics, and electrochemical energy conversion.

The CNST's Energy Research Group offers a supportive research environment with multidisciplinary scientific interactions and access to advanced measurement and nanofabrication capabilities. CNST instrumentation is available to users through collaborations supporting nanomaterials development and applications in several fields.
