“Results & challenges of InAs/InAsSb superlattice growth technology.”
Abstract:One of the most frequently used materials for the detection of mid-wavelength infrared radiation (MWIR) and long-wavelength infrared radiation (LWIR) is mercury-cadmium-telluride (HgCdTe). Despite of many advantages of this material, hazardous materials are used in the HgCdTe production process. Moreover, EU obliged their union members to reduce certain hazardous substances in electrical and electronic equipment by RoHS (restriction of hazardous substances) directive. For that reason, III-V materials like InAsSb are designated to replace HgCdTe from the market. Nowadays, due to improvement of epitaxial techniques [especially molecular beam epitaxy (MBE)], the superlattice (SL) concept presented by Esaki and Tsu in 1970 is being again presented as a potential candidate (proved by many scientific papers) to supersede MCT. During the presentation, the latest results of T2SL technology obtained in the jointed VIGO/WAT laboratory will be presented.UwagaSeminarium w trybie HybrydowymFaculty of Physics room 0.06link to remote mode:https://zoom.us/j/7218838148szczegóły patrz instrukcja :instrukcja: (pdf file)AttentionThe seminar in the Hybrid modeFaculty of Physics room 0.06for details see instruction :
