The experiment that shows the wave nature of electron is Davisson and Germer experiment.
Davisson and Germer made some interesting observation in their experiment. While increasing the accelerating voltage of the electron beam definite peak intensity was observed at a particular voltage. This voltage was found to be 54 volts exactly. The peak cannot be explained by momentum exchanges in electron collisions. The only logical explanation is the constructive interference of electrons scattered from different layers of the crystal. Definitely a wave property.
The De Broglie wavelength associated with this voltage is 0.167 nm. This was exactly the wavelength found theoretically by De Broglie for electron matter waves.
This is how Davisson and Germer experiment explained the wave nature of electron and also found the wavelength associated with the electron as obtained by de Broglie relation.
