Summary: Scanning thermal microscopy (SThM) allows for the measurement of thermal characteristic information from signals obtained by scanning a thermometer probe over a sample surface. In this study, SThM is used to generate sub-wavelength near-field optical images in a plasmonic grating coupler, and it is shown that the dominant component of the SThM signal is from the optical response rather than the thermal response.

Summary: A plasmonic atomic force microscopy (AFM) probe was proposed, utilizing a part of the laser beam to monitor cantilever deflection as the excitation light source. By integrating photonic crystal cavities near the cantilever's free end, a confined hot-spot at the metal-coated tip apex can be induced via transmitted light excitation. Numerical simulations showed that the plasmonic probe can efficiently couple a tilted, linearly polarized beam and achieve a significant local electromagnetic enhancement, making it a powerful tool for simultaneous optical, mechanical, and electrical characterizations.

Summary: The thermophysical properties at the nanoscale are crucial for the operation of nanoscale devices, and scanning thermal microscopy is an effective method to measure thermal transfer phenomena with high resolution. However, with the rapid development of atomic materials, an ultra-sensitive scanning thermal microscopy capable of measuring pico-watt level heat transfer is necessary. This study developed a pW-SThM to measure molecular and atomic-scale phenomena, and demonstrated its ability to detect small differences in local heat transfer in nanodevices and two-dimensional materials.

Summary: Quantitative thermal performance measurements and thermal management at the micro-/nano scale are important due to the shrinking size of electronic components. Scanning thermal microscopy (SThM) accurately reflects changes in local thermal signals based on a thermally sensitive probe. However, the unclear thermal resistance at the probe-sample interface limits the quantitative characterization of thermal conductivity for different materials. This paper analyzes the heat transfer process considering the thermal contact resistance and develops a mathematical function to describe the relationship between sample thermal conductivity and probe temperature.

Summary: The ability of materials to conduct heat is crucial for various physical phenomena, from thermal management to thermoelectrics. Two-dimensional materials like InSe offer a versatile platform to tailor heat transfer due to their high surface-to-volume ratio and mechanical flexibility. Studies show that 2D InSe exhibits anomalous low thermal conductivity compared to traditional dielectrics, making it a promising candidate for future technologies that require efficient heat dissipation or thermoelectric energy conversion.

Summary: Thermoelectric efficiency in thin-film materials can be improved by nanopatterning the surface to reduce thermal conductivity. In this study, nanoscale phononic resonators are introduced to the surface and their potential to reduce thermal conductivity is investigated through experimental and theoretical techniques. Atomistic modeling is used to predict the dependence of thermal conductivity on different design parameters, and this information guides the design and fabrication of silicon fishbone nanostructures.
