摘要: In this chapter we describe and discuss Kelvin probe force microscopy (KPFM), a scanning technique designed to obtain laterally resolved work function images by measuring the electrostatic forces between sample surface. By operating microscope in ultrahigh vacuum, even absolute measurements with very high lateral energy resolution can be realized.
