Title:
FERROMAGNETIC INFLUENCE ON QUANTUM DOTS
Document Type and Number:
WIPO Patent Application WO/2005/109454
Kind Code:
A1
Abstract:
A semiconductor magnetic body comprises a layer (11 15) intended to trap electrons, wherein said layer (11 15) is surrounded on both sides by a magnetic layer (16, 17). This leads to the crea­tion of ferromagnetic character in spatially limited regions of electronic elements such as but not limited to quantum dots, where this creation is achieved using magnetic materials which do not compositionally form part of the region but are rather contained in the zone or zones adjacent to the region.
