    Analysis

    This paper investigates the impact of hybrid field coupling on anisotropic signal detection in nanoscale infrared spectroscopic imaging methods. It highlights the importance of understanding these effects for accurate interpretation of data obtained from techniques like nano-FTIR, PTIR, and PiF-IR, particularly when analyzing nanostructured surfaces and polarization-sensitive spectra. The study's focus on PiF-IR and its application to biological samples, such as bacteria, suggests potential for advancements in chemical imaging and analysis at the nanoscale.

    The study demonstrates that the hybrid field coupling of the IR illumination with a polymer nanosphere and a metallic AFM probe is nearly as strong as the plasmonic coupling in case of a gold nanosphere.

    Analysis

    This paper presents a novel application of Electrostatic Force Microscopy (EFM) to characterize defects in aluminum oxide, a crucial material in quantum computing. The ability to identify and map these defects at the atomic scale is a significant advancement, as these defects contribute to charge noise and limit qubit coherence. The use of cryogenic EFM and the integration with Density Functional Theory (DFT) modeling provides a powerful approach for understanding and ultimately mitigating the impact of these defects, paving the way for improved qubit performance.
