The temperature dependence of the conductance of a quantum point contact has been measured. The conductance as a function of the Fermi energy shows temperature-independent fixed points, located at roughly multiple integers of e2/h. Around the first fixed point at e2/h, the experimental data for different temperatures can be scaled onto a single curve. For pure thermal smearing of the conductance ...
