Summary: The aim of this study is to investigate the bimodal dynamic SThM for nanomachining. A mathematical model for bimodal SThM is provided and compared with the conventional type. It is shown that bimodal excitation increases amplitudes at shifted resonance frequencies. The effects of tip radius on the final surface are also simulated.

Summary: This article introduces a novel ultralarge-area stitchless scanning probe lithography (SPL) and high-throughput in situ characterization system. The system utilizes a scanning probe microscope to generate patterns and nanoscale structures, with a maximum scanning area of 2 x 2 mm. Through an optimized control method, high-bandwidth and high-precision trajectory tracking is achieved. Experimental results demonstrate high nanolithography speed and in situ characterization throughput, opening up new avenues for ultralarge-area nanofabrication and in situ characterization research and applications.

Summary: Understanding light-matter interaction at the nanoscale is achieved by observing fine details of electromagnetic fields. In this study, uncoated fiber probes were used to minimize the perturbation to the electromagnetic fields. The experiments and simulations showed that the uncoated probes allowed for clear nearfield details with high optical resolution.

Summary: Nanoscale low-dimensional chiral architectures have attracted increasing scientific interest due to their potential applications in chiral recognition, separation, and transformation. In this study, large-area two-dimensional chiral networks on Au(111) and one-dimensional metal-liganded chiral chains on Cu(111) were successfully constructed and characterized. The chiral transformation of the chiral networks on Au(111) was analyzed, and the electronic state information was studied using scanning tunneling spectroscopy. The combination of scanning tunneling microscopy and non-contact atomic force microscopy techniques enabled ultra-high-resolution characterization of chiral structures on low-dimensional surfaces.

Summary: The ultrafast pump-probe microscope was used to investigate the ultrafast dynamics of photoexcited carriers and phonons in InSb, revealing the delocalized electron-phonon coupling and localized recombination of electrons and holes. The study also demonstrated the manipulation of phonon properties through an applied electric field, leading to the first observation of spatial breadth of phonons in InSb with large carrier concentrations.

Summary: The growth of lateral heterostructures of graphene and h-BN on Rh(110) surfaces is reported, enabling control over the rotational order of the domains. Perfect lateral matching is observed at the boundaries, and intervalley scattering processes in graphene regions can be observed. These high-quality heterostructures with tunable properties can be used as test beds for developing novel nanomaterials.

Summary: A full understanding of hydrogen embrittlement mechanisms requires knowledge of local hydrogen distribution. Grain boundaries are one of the microstructural features where hydrogen segregates, leading to a transition from transgranular to intergranular fracture. The type of grain boundary affects the segregated hydrogen and its diffusion rates. Scanning Kelvin Probe Force Microscopy (SKPFM) is a tool that can qualitatively measure local hydrogen contents, and potentially quantitatively in the future. This study uses SKPFM to detect hydrogen at grain boundaries in situ in a permeation setup, and investigates the influence of operation mode and atmosphere on the Contact Potential Difference V-CPD.
