for me it looks like a plates capasitor with a potential between two plates maybe because they made of different materials copper and aluminum (like very slow battery)
and between the plates instead of air or empty space there is a semiconductor material mixed with insulator (am i correct, why it is mixed).


also this thing reminds me of John Hutchison's battery as acceleration of electrons of the external filed as electron cascade effect. because crystals have a magnification effect on flow of electrons.

1. how would you build an ELECTRON FIELD GENERATOR in today's reality.
today we have semiconductors and more understanding about semiconductors.

2 how can i to build  ELECTRON FIELD GENERATOR at home most easyly.
