GaAs quantum wells

  1. Feb 13, 2015 #1
    Hi guys! i have some troubles with my analysis on a GaAs quantum wells emission spectrum! I made this program on excel capable of predict heavy and light transitions and expected heavy transitions are like perfectly matched, while there are about 20-30% of errors on light transitions.

    My program works with experimental data of bulk GaAs band structure, so my explanation up to now is to suppose a warping on the light band with the transition to 3D to 2D behaviour capable of changing the effective mass and/or the gap, does anyone know something about? (the thicker the well, the bigger the error)

    thank you very much!!

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    I do come to new conclusions days ago! for everyone interested, the reason is in fundamentals of semiconductor

    (there are important warping in both heavy and ligth bands and a rupture of degeneration when confining the system in a quantum well)
