摘要

计算了在异质结中形成的二维电子气体中声子通过变形势和压电相互作用散射引起的回旋共振线宽。考虑了由于自由载流子的存在，波函数沿量化和筛选方向的有限范围。计算得到的变形势声子散射线宽随磁场的变化呈B12的变化。然而，由于压电声子散射，线宽的场依赖性较弱。

Cyclotron resonance linewidth in a two-dimensional electron gas due to phonon scattering

Cyclotron resonance linewidths due to scattering by acoustic phonons via deformation potential and piezoelectric interaction have been calculated for a two-dimensional electron gas formed in heterojunctions. The finite extent of the wave function along the direction of quantisation and screening due to free carriers are considered. The calculated linewidth for scattering due to deformation potential acoustic phonons show a $B^{12}$ variation with magnetic field. The field dependence of the linewidth due to piezoelectric phonon scattering is however weaker.
