本文研究了温度T与弹性平均自由时间τ之间任意关系时，电子-电子相互作用对二维电子气霍尔系数随温度变化的影响.在小的温度T τ远小于（h）在酒吧，我们重现霍尔系数和纵向电导率的对数温度依赖性之间的已知关系。在较高的温度下，这种关系很快就被破坏了;霍尔系数的修正与1/T成正比，而纵向电导率与温度成线性关系。
We investigate the effect of electron-electron interaction on the temperature dependence of the Hall coefficient of two-dimensional electron gas at arbitrary relation between the temperature T and the elastic mean-free time tau. At small temperature T tau much less than(h) over bar we reproduce the known relation between the logarithmic temperature dependences of the Hall coefficient and of the longitudinal conductivity. At higher temperatures, this relation is violated quite rapidly; correction to the Hall coefficient becomes proportional to1/T whereas the longitudinal conductivity becomes linear in temperature.
