WebMar 6, 2024 · Colloidal InAs nanocrystals (NCs) are among the most promising light emitters in the short-wavelength infrared (SWIR) range. These InAs NCs are eligible to … WebOct 15, 2015 · We investigated the effects of the GaAs capping temperature on the morphological and photoluminescence (PL) properties of InAs quantum dots (QDs) on GaAs(001). The broadband tuning of the emission wavelength from 1.1 to 1.3 μm was achieved at room temperature by only adjusting the GaAs capping temperature. As the …

WebOct 6, 2024 · This topic specifically calls for development, demonstration and implementation of a non-destructive, quick-turn, full-wafer screening capability. The proposed solutions should be capable of non-destructively measuring the bandgap and the minority carrier lifetime of the T2SL absorber layers and their uniformity across the wafer … WebThe results showed that different interface structure can also influence the band structure, leading to the changes of cutoff wavelength. For the same InAs/GaSb superlattice material fully compensated with InSb interface, one with symmetric InSb interfaces has shorter cutoff wavelength than superlattice with asymmetric interfaces. 展开 how to style wide leg knit pants
