Methods of doping semiconductor materials and metastable doped semiconductor materials produced thereby

摘要

The structures of base semiconductor materials such as Si are modified by the use of isotope transmutation alloying. A radioisotope such as Si³¹ is added into a base semiconductor material such as Si, and the radioisotope is transformed to a transmuted form within the crystal lattice structure of the base semiconductor material. A master alloy comprising a relatively large amount of radioisotope such as Si³¹ may initially be made, followed by introduction of the master alloy into the base semiconductor material. When Si³¹ is used as the radioisotope, it may be transmuted into P³¹ within an Si crystal lattice structure. Metastable semiconductor materials doped with otherwise insoluble amounts of selected dopants are produced as a result of the transmutation process.
