摘要:
在有效质量近似下,通过自洽计算求解薛定谔方程和泊松方程,得到了温度不为零时Si δ掺杂的GaAs量子阱系统的电子态结构.研究了温度和掺杂浓度对系统子带能量、费米能级、电子密度分布和子带间光学吸收系数的影响.发现在一定的掺杂浓度下,费米能级会随着温度的升高而降低,子带间入射光总的吸收系数随温度升高而降低; 在温度一定时,费米能级和子带能级随掺杂浓度的增大而增大,子带间入射光总吸收系数随掺杂浓度增大而增大.
Abstract:
By solving Schr?dinger equation and Poisson equation self-consistently under the effective mass approximation,we calculated the structure of the electronic state of Si δ-doped GaAs quantum well system at T≠0.We studied the effect of temperature,doping concentration,and energy of incident light on the intersubband energy,Fermi energy,electron concentration distribution and intersubband optical absorption coefficient.It is found that at the given doping concentration,the Fermi energy decrease with the increase of temperature,the total intersubband optical absorption coefficient decrease with the increase of temperature.And at the given temperature,the total intersubband optical absorption coefficient increase with the increase of doping concentration.
