WebApr 22, 2024 · Semiconductor superluminescent light-emitting diodes (SLEDs) have emerged as ideal and vital broadband light sources with extensive applications, such as optical fiber-based sensors, biomedical sensing/imaging, wavelength-division multiplexing system testing and optoelectronic systems, etc. Self-assembled quantum dots (SAQDs) … WebJan 1, 2024 · The explicit compound quantum well consists nominally of a 10 nm GaSb and a 13 nm InAs well. On top a 100 nm AlAs 0.08 Sb 0.92 barrier and a 5 nm GaSb cap finish the structure. The composition of the QW widths aims at an inversion of the electron and hole subbands. 8 × 8 kp simulations suggest an inversion of about 70 meV at k=0. WebA new measure to enhance the performance of InAs quantum dot solar cell is proposed and measured. One monolayer AlAs is deposited on top of InAs quantum dots (QDs) in multistack solar cells. The devices were fabricated by molecular beam epitaxy. In situ annealing was intended to tune the QD density. A set of four homes for sale near crown point indiana
