Functional Hybrid Nanomaterials

Group Focus and Capabilities Overview
To understand and control nanomaterials synthesis and assembly to elicit special functionalities by integrating real-time diagnostics and advanced characterization techniques.

Functional Hybrid Nanomaterials

Conducts controlled synthesis and processing of nanomaterials, thin films, and functional hybrid architectures by PLD, CVD, Sonospray, and transfer stamping.  The group specializes in optical spectroscopy characterization, both in situ of the processing environment and growing material during synthesis as well as ex situ and in operando via Raman, PL, SHG, vis-UV, and reflectance spectroscopies to map 2D materials and develop optoelectronic, sensing, and catalytic functionalities.  Raman and PL microspectroscopy is performed in several different environments, ranging from versatile rapid mapping capabilities to measurements with tunable sources for low-frequency modes at cryogenic temperatures.  Ultrafast laser spectroscopy is used to measure quasiparticle dynamics, and new ultrafast cathodoluminescence spectroscopy with nm-resolution is coupled with single superconducting nanowire detection for quantum correlation measurements of single photon emitters.  Multimodal ‘lab on a crystal’ QCM-based platforms are used to correlate electrical, optical, and gravimetric/viscoelastic properties of thin films with environmental effects using AI and ML.  A full suite of heterogeneous catalysis and photocatalysis measurements are also offered.  Capabilities available to users include:
