Optimization of qPlus sensor geometry and circuit for high-speed atomic force microscopy in liquid environments
Takashi Ichii, Shuji Tokitoh, Yuto Nishiwaki +1
Atomic force microscopy (AFM) using qPlus sensors is a powerful tool for high-resolution analysis in various liquids, including high-viscosity or opaque environments. However, the…
High-Temperature and High-Speed Atomic Force Microscopy Using a qPlus Sensor in Liquid via Quadpod Scanner and Hybrid-Loop Frequency Demodulation
Yuto Nishiwaki, Toru Utsunomiya, Takashi Ichii
Atomic-resolution imaging on molten metal/solid interfaces at temperatures above 200 °C was achieved using a high-temperature, high-speed atomic force microscope (AFM) equipped wit…
One-step Fabrication of Sharp Platinum/Iridium Tips via Amplitude-Modulated Alternating-Current Electropolishing
Yuto Nishiwaki, Toru Utsunomiya, Shu Kurokawa +1
The platinum/iridium (Pt/Ir) alloy tip for scanning probe microscopy (SPM) was fabricated by amplitude-modulated alternating-current (AC) electropolishing. The clean tips with a ra…
Interaction between substrate and probe in liquid metal Ga: Experimental and theoretical analysis
Ken-ichi Amano, Kentaro Tozawa, Maho Tomita +6
Understanding the interaction between two bodies in a liquid metal is important for developing metals with high stiffness, strength, plasticity, and thermal stability. We conducted…
