基于局域态位于导带下方的模型，针对低/中磁场确定了二维电子系统磁导的密度和磁场依赖性。当根据电子密度绘制时，磁导显示出一个宽的最大值，该最大值向更大的电子密度移动，并且当磁场增加时降低。还导出了电阻率、态密度、有效质量和弛豫时间的公式。
Based on a model in which a localised state lies below a conduction band, the density and magnetic field dependences of the magnetoconductance of two-dimensional electron systems are determined for low/intermediate magnetic fields. When plotted against electron density, the magnetoconductance shows a broad maximum which is shifted towards a larger electron density and lowered when the magnetic field is increased. Formulae for the resistivity, density of states, effective mass and relaxation time are also derived.
