Latest Patents

Evans' latest patents include a method of fabricating a superlattice structure. This innovative method involves introducing atoms of a first III-V semiconductor compound into a vacuum chamber, allowing for uniform deposition on a substrate. Additionally, atoms of at least one more III-V compound are introduced to create a repeating superlattice structure of alternating thin layers. The introduction of surfactant atoms, preferably bismuth, enhances the quality of the resulting superlattice structure. This method is particularly useful for forming components of infrared photodetectors.

Another significant patent focuses on the superlattice structure itself, which consists of an InAsSb layer adjacent to a GaSb layer. The adjacent layers repeat to form a superlattice, ideally arranged to minimize strain. This unstrained superlattice structure is designed to improve performance in infrared photodetector applications.
