Priority-Claim Claim No: 16/556,899 Discovery of a new far-infrared absorption band and an idea for a far-infrared detector using said absorption band

Claimants: Mark Simpson & Alice Carr (of University of M.) Application No: 16/556,899 Publication Date: August 14, 2015 Scientific Fields: Physics >> Optics >> Optical detectors The above claimants assert that, according to their knowledge, they are the first to conceive the ideas & discoveries recited hereinafter: A. Formal Claims 1 to 5: Claim 1: I claim the discovery of a new optical absorption band in the far-infrared region at the InSb interface of the InAs/GaSb hetero-structures, wherein the infrared photons absorption is due to the electronic transitions between valence band states in the GaSb and conduction band states in the InAs; wherein the energy of the absorbed photons is from about 20meV to 50meV at room temperature; wherein the energy of the absorbed photons can be adjusted from about 10meV  to about 200meV in magneto-optical transmission experiments conducted between 1.2T to 3T. Claim 2: We claim an idea for a new type of far-infrared photo-detector based on the optical absorption phenomenon disclosed at claim 1, the photo-detector would have the characteristics and would work as described in the following:  the photo-detector would comprises an InAs/GaSb heterostructure; the far-infrared photons incident on the InAs/GaSb heterostructure would be absorbed by electrons in the GaSb valence band thereby causing a transition of the electrons to the InAs conduction band; the electrons transitioned in the InAs conduction band can move much easier into the InAs layer than in the GaSb layer because of the much higher mobility of the electrons in the InAs than the holes in the GaSb; the surplus of electrons created in the InAs by the far-infrared photons increases the overall conductivity of the InAs/GaSb heterostructure which thereby can be translated into an increase of the current collected when a voltage is applied along the interface. see all claims B.
