Process for Producing an Electroluminescent P-N Junction Made of a Semiconductor Material by Molecular Bonding

摘要

A method for making an electroluminescent PN junction includes molecular bonding a face in a crystalline semiconducting material doped with a first type of a first element with a face in a crystalline semiconducting material doped with a second type opposite to the first type, of a second element, at a bonding interface. The semiconducting material has an indirect forbidden band. The crystalline lattices shown by the faces are shifted in rotation by a predetermined angle so as to at least cause formation of a network of screw type dislocations at the bonding interface.
