PeakForce Kelvin probe force microscopy

21 Jun 2023

Kelvin probe force microscopy (KPFM), also called surface potential microscopy, has found broad applications, ranging from corrosion studies of alloys, photovoltaic effects on solar cells, and surface analysis. KPFM, together with conductive atomic force microscopy (AFM), has been recognized as the two most used nanoscale electrical characterization tools, complementing each other. In this application note from Bruker, explore how limited spatial resolution and lack of measurement repeatability and accuracy have limited KPFMs usefulness in some critical areas, such as in the identification of donor and acceptor domains in bulk heterojunction organic solar cells, material differentiation in composite materials, and trapped charges on insulators.

Dimension FastScan™

Bruker Nano Surfaces and Metrology

World's Ultimate AFM The new benchmark for speed with highest resolution and performanceThe Dimension FastScan™ delivers, for the first time, extreme imaging speed without loss of resolution, loss of force control, added complexity, or additional operating costs.This tip-scanning system provides measurements on both large and small size samples in air or fluids. With the FastScan you can achieve immediate atomic force microscopy images with the expected high resolution of a high-performance AFM, all in a single system. Whether surveying a sample scanning at >125Hz to find the region of interest, or scanning for detail at 1-second per image frame in air or fluids, the Dimension FastScan will redefine your AFM experience.Dimension FastScan™ Features: Work hundreds of times faster with fast scanning rates up to frames per second, automated laser and detector alignment, comprehensive work flow and smart engaging Built-in measurement automation software in conjunction with higher speed ScanAsyst® provide exceptional measurement confidence and repeatability Precise force control at the tip renders high resolution and long tip-life Low-noise, temperature-compensated sensors in the scanners maintain sub-nanometer noise levels Closed-loop Icon and FastScan scanners keep vertical noise below 30pm and 40pm, respectively, as well as high accuracy with ultra-low drift Sample from subnanometer to hundreds of nanometers in height without loss of resolution
