摘要:
The invention is directed to a spin-polarized electron injector using a semiconductor tip, in which tip the injected electrons are photocreated by a circularly polarized light excitation incident on the rear of the tip. This tip is supported by a transparent lever or cantilever and undergoes a surface treatment for the purpose of removing the surface oxide layer, to prevent said layer from reforming and to improve the proportion of injected electrons.
