Abstract

The substitution of hot filaments by field-effect microtips has several advantages in many electronic applications. LETI has already proved the interest of this principle for flat panel displays; many people believe it could also provide novel microwave sources. Moreover, the properties of the emission enable to seek new electron optics applications that were not possible with hot filaments. An interferometry experiment was designed, developed and characterized in order to evaluate the potential of the microtips fabricated in the LETI for such applications. This experiment is composed of a Mollenstedt biprism, of electrostatic lenses and an imaging system composed of deflection plates, a small aperture diaphragm (1 {mu}m) and a channel electron multiplier. Quantum wave effects have been observed, which confirms the good coherence properties of the source. Moreover, this experimental setup enables to better understand the physical phenomenon of the emission of the tips fabricated in the LETI, and to propose some technological improvements for the applications we seek. It is also designed for electron holography applications, and should allow the study of new compact electron optics apparatus taking account of the wave properties of the electrons emitted by microtips.
