Quantitative Characterization of Platinum Diselenide Electrical Conductivity With an Inverted Scanning Microwave Microscope

Gianluca Fabi et al.

Summary: This study presents an approach to quantify sample properties using an inverted scanning microwave microscope (iSMM) and analyzes the local electrical conductivity of a platinum diselenide sample, confirming its semimetal behavior. The method is validated using a full-wave numerical model and provides calibration procedures for transmission and reflection mode measurements, enabling high-frequency quantitative characterization of a wide variety of samples and surfaces.

Attoampere Nanoelectrochemistry

Simon Grall et al.

Summary: Electrochemical microscopy techniques have expanded the understanding of surface chemistry to micrometer and sub-micrometer levels. This study introduces local cyclic voltammetry measurements with sub-atto-Ampere sensitivity and spatial resolution < 80 nm at the solid-liquid interface on a ferrocene self-assembled monolayer. The high sensitivity is achieved through measurements of the charging of the local faradaic interface capacitance at GHz frequencies, allowing for nanometer-scale details of different molecular organizations with minimal dispersion in molecular electrical properties.
