Abstract
An emission instability attributed to an oxide layer on a silicon emit ter tip surface has been characterized. The instability leads to a cur rent runaway which often results in device failure. When device failur e does not occur, the instability is a one time event while the device remains in a vacuum environment. The magnitude of the instability inc reases with increasing oxide thickness and can be effectively eliminat ed by etching in buffered HF immediately before testing or device pack aging.
