A High-Throughput Optical Microscopy Approach to Correlate the Surface Topography of Materials and Their Energy Conversion Properties
An approach to combine functional data with structural data for a wide range of materials. Particularly useful for ultrathin nanosystems such as 2D transition metal dichalcogenides (MoS2) and perovskite photovoltaics. The method incorporates novel software as well as hardware modifications.

At A Glance
- Overlays structural (e.g., electron, scanning probe, or optical microscopy images) and functional images (e.g., PL, Raman, Photocurrent images).
- Quantitative / seamless process
- Useful for a variety of industries
Many industries and research domains measure functional signals (Ex: light emission, photo-induced current) using focused laser beams. No technique exists to date to overlay those images with topographical data seamlessly and quantitatively.
Novel algorithms along with hardware modifications to the microscopic / spectroscopic apparatus allows for the collection and processing of reflected laser signal. The captured signal is used to create a topographical map (C) of the sample. That map is then seamlessly overlaid onto the functional data image (B) to create a composite image (D).
- Fast, efficient screening of materials
- Simple modification to existing designs
- Allows for easy to see structure-function relationships
