Suppression of phonon-mediated hot carrier relaxation in type-II InAs/AlAs${}_x$Sb${}_{1-x}$ quantum wells: a practical route to hot carrier solar cells

H. Esmaielpour, V. R. Whiteside, J. Tang +6

InAs/AlAs${}_x$Sb${}_{1-x}$ quantum wells are investigated for their potential as hot carrier solar cells. Continuous wave power and temperature dependent photoluminescence indicate…
