Abstract
The dynamic characteristics of field electron emission from the layered structures with quantum wells have been qualitatively analysed. The main factor leading to appearance of the high frequency current oscillation is the negative differential resistance, observed under rather high electrical field. Layered structures with superthin barriers (like Si - SiO2 - δSi - SiO2) seems to be likely to show this effect. The very narrow resonance peak in the FE-current from QW system at the definite external fields have been demonstrated
