摘要：
The line broadening of intersubband transitions in In0.53Ga0.47As/In0.52Al0.48As quantum wells is analysed within the microscopic pseudopotential approach, that implicitly takes all the band structure effects into account. Linewidths considerably broader than those in the conventional GaAs/AlxGa1-xAs quantum wells are found, indicating that these new type of quantum wells should be advantageous only when larger transition energies are necessary.
