为了研究费米液体的表面元激发,我们测量了~ 3 He,μ ~ 3上的表面态电子迁移率。低于300 mK时,μ3的逐渐增加归因于电子被涟波子散射。在100 mK以下的3 He中确实存在涟漪。我们观察到μ3的突然减小,这是由于向维格纳固体(WS)的转变。WS的电导率和迁移率对温度和磁场的依赖性不同于液体4 He的SSE行为。
We have measured the mobility of surface state electrons (SSE) on liquid3He, μ3, aiming to study the elementary surface excitations of the Fermi liquid. A gradual increase of μ3 below 300 mK is attributed to the scattering of electrons by ripplons. Ripplons do exist in3He down to 100 mK. We observe an abrupt decrease of μ3, due to the transition to the Wigner solid (WS). The dependences of the WS conductivity and mobility on temperature and magnetic field differ from the SSE behavior on liquid4He.
