Abstract :
Temperature- and excitation-dependent modulated photoluminescence measurements are performed on narrow-gap liquid phase epitaxy (LPE) Hg1-xCdxTe (MCT). By combining with the second-order derivative and curve fitting, the band-acceptor transition is identified which is related to Hg vacancies. The energy level of this Hg vacancy locates at 12 meV (at 11 K) above the valence band.
