Field emission microscope

A field electron microscope utilizes a strong electric field to cause the emission of electrons from a metal tip. The electron beam is accelerated and bombards the sample surface, generating secondary electron or backscattered electron signals, which are then imaged by a detector. It is used to observe material surface morphology and composition distribution, with applications in nanomaterials and semiconductor defect analysis.
Selection
Configure the vacuum level based on the sample's conductivity; samples with poor conductivity require a low-vacuum mode. Select the electron gun type according to resolution needs: a tungsten filament gun meets routine observation requirements, while a field emission gun is suitable for atomic-level observation. Choose a compatible sample stage based on the sample chamber size, and consider accessories like energy-dispersive spectrometers to extend elemental analysis capabilities.
