This book introduces some alternative methods for enhancing the
performance of In(Ga)As/GaAs-based quantum dot infrared
photodetectors (QDIPs). In(Ga)As/GaAs-based QDIPs and focal plane
array (FPA) cameras have wide application in fields such as
military and space science. The core of the study uses a
combination of quaternary In0.21Al0.21Ga0.58As and GaAs spacer as a
capping layer on In(Ga)As/GaAs quantum dots in the active region of
the detector structure. For the purposes of optimization, three
types of samples growths are considered with different capping
thicknesses. The results presented include TEM, XRD and
photoluminescence studies that compare combination barrier
thickness and its effect on structural and optical properties.
Compressive strain within the heterostructure, thermal stability in
high temperature annealing, spectral response, shifts in PL peaks
peak,and responsivity and detectivity are all considered. The
results also present a narrow spectral width that was obtained by
using InAs QDs which is very useful for third generation FPA camera
application. The book details effect of post-growth rapid thermal
annealing on device characteristics and methods to enhance
responsivity and peak detectivity. The contents of this book will
be useful to researchers and professionals alike.
