Origin: Research Instrument Invented By Scientists at JPL&apos;s Center for Microelectronics
BEEM (Ballistic Electron Emission Microscopy) was invented at Jet Propulsion Laboratory&apos;s Center for Microelectronics Technology. It is a significant research instrument for microelectronics research because it is able to image underlying layers or interfaces of surface structures. A tiny current is injected into a metal layer and the electrons travel ballistically through the metal allowing the researcher to study the operation and performance of a structure. Other advantages include nondestructive imaging of barrier heights and electronic characterization of devices, as well as the potential to observe processes like molecular beam epitaxy (crystal growth) in situ.
