Latest Patents
One of his latest patents is titled "AlSb lattice matched barrier infrared detector to improve quantum efficiency and process yield." This invention features an AlSb lattice matched barrier infrared detector architecture that utilizes an AlSb binary barrier layer. This design allows for the implementation of strain layer superlattice absorbers with higher absorption coefficients, leading to improved quantum efficiency. The structure simplifies the epitaxial growth process and enables the use of bulk InAsSb absorber material with a 5.0 µm cutoff for both single and dual color devices. The infrared detector is formed by growing the detector material, which includes a bottom contact, absorber layers, an AlSb barrier, an optional graded layer, and a top contact, all on top of an AlSb lattice matched buffer layer. This method facilitates the deposition of unstrained bulk InAsSb and InAs/InAsSb superlattice absorbers with a continuously tunable cutoff from mid-wavelength to long-wavelength infrared.
Another notable patent is the "Method of passivating and encapsulating III-V surfaces." This method focuses on producing a surfaced passivated, encapsulated surface III-V type II superlattice (T2SL) photodetector, specifically a p-type heterojunction device. The process involves cleaning, etching, and exposing the surface of a III/V material to solution mixtures that simultaneously remove oxides and encapsulate the surfaces.
