We report on the observation of a very strong, broad and asymmetric H-band photoluminescence (PL) spectrum in silica delta-doped p-type Al0.35Ga0.65As-GaAs heterojunctions (SHs). Doping type (n- or p-type) dramatically changes the H-band PL emission. When optical excitation intensity increases by two orders of magnitude, a redshift of H-band in the delta-doped p-type SH is as large as 27 meV. The results of self-consistent calculation of coupled Schrodinger and Poisson equations and PL analysis indicate that the H-band originates from effective band-gap renormalization due to two-dimensional hole-gas.
