Experimental evidence of nonuniform carrier distributioninmultiple-quantum-well laser diodes

This is the authors' abstract. We don't add key points for this paper.

Carrier distribution in multiple quantum wells is studied. Nonuniform carrier distribution is evidenced by the lasing characteristics of laser diodes with multiple quantum wells of different widths. It is shown that the well sequence significantly influences the threshold current and the characteristic temperature owing to nonuniform carrier distribution.
