Bias and temperature dependence of the 0.7 conductance anomaly in Quantum Point Contacts

Phys. Rev. B 62, 10950 - 10957 (2000) The 0.7 (2e^2/h) conductance anomaly is studied in strongly confined, etched GaAs/GaAlAs quantum point contacts, by measuring the differential conductance as a function of source-drain and gate bias as well as a function of temperature. We investigate in detail...
