XRD rocking curves of the as-grown (asgr.) and annealed (ann.) QWIP structures and the dynamical simulated (sim.) pattern of the as-grown sample (dashed line). The curves are vertically shifted for clarity.
Photoluminescence spectra of the as-grown and annealed GINA QWIP structures measured at . The spectra are vertically shifted for clarity. The arrows together with the energy values show the energy positions of the PL peaks.
Photocurrent spectra of the as-grown GINA QWIP measured (a) at different bias voltages at (b) at different temperatures at . The arrow shows the theoretical results obtained from the ten-band calculation.
