Applications
Surface Sensitivity of PiFM
Since photo-induced force (PiF) is generated from the tip-enhanced field, which extends only about 20…
Study of Organic-Inorganic Compound vs PiFM
Block-selective infiltration with inorganics such as metal oxides on self-assembled block copolymer patterns should provide…
Spatial Resolution of PiFM
PiFM achieves excellent spatial resolution. Since our Science Advances paper [1], we have enhanced the…
Atomic-level Processing
As integrated circuit devices continue to shrink, surface layers have become a significant fraction of…
Nanoscale Protein Analysis
Tau protein is known as a microtubule-stabilizing factor.1 Tau is a microtubule-associated protein (MAP) which…
Cross-sectional IR PiFM Analysis
Multi-layers of different materials find usage across various applications. The thicknesses of the layers range…
Chemical Mapping
Advances in nanotechnology have intensified the need for analytical tools that can chemically characterize newly…
Understanding PiF-IR Spectra
IR PiFM, with its ~5 nm spatial resolution holds tremendous potential for nanoscale chemical analysis. One…
3D Nanoscale Analysis of Polymer Systems
In this note, we will demonstrate the elegance and utility of the technique by analyzing amphiphilic siloxane-polyurethane (AmSi-PU) coatings...
PiFM Imaging of Latent EUV in t-BOC CA Resist
On EUV exposure of t-BOC resists, topographic differences arise between exposed and unexposed masked areas.…
PiFM and Multimodal Imaging of HAMR Devices
Topography, PiFM, and s-SNOM (at one harmonic of the dither frequency) images are acquired concurrently…
Surface Plasmon Polaritons Visualized with PiFM
Surface plasmon polaritons (SPP) at the gold-air surface imaged via PiFM. p-polarized 809 nm laser…
