Progress in nanotechnology is enabled by and dependent on the availability of measurement methods with nanoscale resolution. The goal of the nanoscale chemical imaging program in the Center for Nanoscale Science and Technology (CNST) is to develop measurement tools and methods to characterize and understand the chemical composition of materials at the nanoscale.
State of the art research facilities include two atomic force microscopes (AFMs) and wavelength tunable lasers covering a spectral range from 400 nm and 16.00 µm continuously. this setup enables the acquisition of absorption spectra and images with nanoscale resolution using the photothermal induced resonance technique (PTIR).
Current research goals are the improvement of the instrumentation and the development of novel nanoscale tools to characterize multiple materials properties (chemical, thermal etc.) simultaneously. These novel techniques are applied to characterize advanced materials such as (1) photovoltaics, (2) plasmonics, (3) metal-organic frameworks, and (4) two-dimensional materials.
The CNSTs 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.
