Kelvin probe force microscopy (KPFM), also known as surface potential microscopy, is a noncontact variant of atomic force microscopy (AFM). By raster scanning in the x,y plane the work function of the sample can be locally mapped for correlation with sample features. When there is little or no magnification, this approach can be described as using a scanning Kelvin probe (SKP). These techniques are predominantly used to measure corrosion and coatings.

  • Die Raster-Kelvin-Mikroskopie (oft KPFM oder KFM abgekürzt vom englischen Begriff Kelvin (Probe) Force Microscopy, manchmal auch SKPM – Scanning Kelvin Probe Microscopy) ist ein Verfahren zur Messung des lokal aufgelösten einer Probe. Entwickelt wurde die von der Rasterkraftmikroskopie (AFM) weiterentwickelte Messmethode durch Nonnenmacher, O’Boyle und Wickramasinghe in den 1990er Jahren. Neben klassischen materialwissenschaftlichen Fragestellungen wie z. B. im Bereich der Solarzellenentwicklung oder Korrosionsforschung wird KPFM inzwischen auch mehr und mehr im Bereich der Biologie angewendet. (de)
  • ケルビンプローブフォース顕微鏡(ケルビンプローブフォースけんびきょう、英: Kelvin probe Force Microscopy: KFM)は、原子間力顕微鏡 (AFM) を元に開発された顕微鏡の一種。イギリスのケルビン卿が接触電位差として短針と試料との電位差が得られることを発見した事が名前の由来となっている。 (ja)
  • 开尔文探针力显微鏡(Kelvin probe force microscope, KPFM)是一種原子力顯微鏡,於1991年問世。开尔文探针力显微鏡利用微懸臂感受和放大懸臂上尖細探針與受測樣品原子之間的作用力,從而達到檢測的目的,具有原子級的分辨率。 (zh)

  • A microscopia Kelvin (KPFM – Kelvin probe force microscopy) ou também chamada microscopia de potencial de superfície proposta por Nonnermacher em 1991, é uma técnica de resolução atômica e nanométrica sendo uma variante da microscopia de força atômica onde um cantilever metalizado é capaz de medir a diferença de potencial entre a ponteira nele contido e a superfície da amostra. Através desta medição, pode-se obter a função trabalho característica de cada átomo da superfície da amostra o que dá a exata composição em nível atômico da superfície da amostra. (pt)
