What Does FERP Stand For?

FERP stands for Field Emission Retarding Potential

FERP, or Field Emission Retarding Potential, refers to the voltage applied in field emission systems that counteracts the kinetic energy of electrons emitted from a material's surface. This potential plays a critical role in enhancing the efficiency and control of electron emission processes, often utilized in applications such as electron microscopy and nanofabrication. By optimizing the retarding potential, researchers can improve the resolution and performance of electron-beam technologies.
