abstract = "The quantization of conductance in units of 2e 2/h of a quantum point contact (QPC) under low temperature, a narrow way formed in a two-dimensional electron gas (2DEG), has become a paradigm of mesoscopic physics. Devices defined by electrostatic gates in GaAs/AlGaAs 2DEGs display an extraordinary variety of spin related phenomena. Besides the usual conductance plateaus, QPCs show an extra plateau at ∼0.7(2e 2/h), believed to arise from electron-electron interactions. These plateaus disappear as temperature rise. We present the experimental results of temperature dependent disappearance. Under magnetic fields plateaus shift due to the Landau level. The numerical results using Green's function approach is also presented.",
