Energy shift for a GaInAsSb bulk sample as measured by photoluminescence at . The sample was annealed for at (dotted line). A blueshift of and a strong increase in intensity was found, but no significant change in the FWHM.
Blueshift for a GaInAsSb MQW sample as measured by photoluminescence at , if annealing time and temperature were changed. The sample was grown at .
Blueshift for an annealed GaInAsSb MQW structure as measured by photoluminescence at . An almost linear behavior of the wavelength shift with temperature can be seen. The open circle refers to the unannealed sample. All samples were annealed for .
FWHM for a GaInAsSb MQW structure determined by photoluminescence at . The samples were annealed for . The unannealed sample is referred to the open circle. The FWHM increases to a value of about between 450 and . If annealed at more than , the FWHM drops to the unannealed value or below. The error bars result from different measurements on the same sample.
Blueshift for GaInAsSb MWQ samples as measured by photoluminescence at . All samples were annealed for 2 at . The full width at half maximum (FWHM) is given before (1) and after annealing (2), respectively.
