Abstract:
Spire Semiconductor proposes a novel MOCVD growth scheme that will substantially reduce the production costs of inverted multi-junction solar cells. Incorporating quantum well structures will be investigated as a means to improve device efficiency and end of life cell performance in the space… More
Dark current plays an essential role in the performance of LWIR InAs/GaSb SL-based FPAs. Previous improvements in material quality and device design have significantly suppressed bulk contributions to the dark current. The dark current due to surface defects becomes prominent with decreasing… More

Award Amount:$79,593.00
Abstract:
Spire Semiconductor proposes to make InAs/GaSb based MWIR/LWIR dual-band FPA photodetectors with low surface-leakage current using the unique processing and passivation techniques developed at Spire Semiconductor. In phase I, Spire Semiconductor will demonstrate FPA pixel-sized (~30x30um-2)… More
Spire Semiconductor proposes to make an InGaAs-based three-junction (3J) tandem thermophotovoltaic (TPV) cell to utilize more of the blackbody spectrum (from a GPHS) efficiently. Semi-insulating InP wafers will be used for monolithically integrated module (MIM)compatibility and to achieve low… More
