Probe Current In Scanning Electron Microscopy at Bob Bruce blog

Probe Current In Scanning Electron Microscopy. Probe size, shape, and current are important parameters for the performance of all probe forming systems such as the scanning. The goal of the sem is to scan a focused beam of primary electrons onto a sample, and to collect secondary electrons emitted from the sample. Namely, as the probe diameter is reduced, the probe current is reduced. The sharpness, contrast and depth of field depends upon three major electron beam parameters, i.e. The probe current and the probe diameter are in the relation shown in fig. Probe current means an electron beam focused on a specimen. Working with the specimen, probe current emits electrons. It is therefore necessary to select a. Electron probe size (d p),. Scanning coils above objective lens raster beam on sample. In this article we examine scanning probe microscopy/atomic force microscopy (spm/afm), scanning electron microscopy. For sem, probe current and spot size are practically viewed as equivalent and interchangeable nomenclatures. Condenser lens system defines probe size and control probe current.
