摘要: The electroluminescence of a quantum-dot (QD) laser diode was found to blueshift as the injection current is increased. carrier distribution within QD layers modeled and Stark shift, measured from photocurrent, used explain large seen in electroluminescence. built-in electric dipole be dependant on growth conditions.
