Tracking the energies of one-dimensional sub-band edges in quantum point contacts using dc conductance measurements
2011
Journal of Physics: Condensed Matter
The semiconductor quantum point contact has long been a focal point for studies of one-dimensional electron transport. Their electrical properties are typically studied using ac conductance methods, but recent work has shown that the dc conductance can be used to obtain additional information, with a density-dependent Landé effective g-factor recently reported [T.-M. Chen et al, Phys. Rev. B 79, 081301 (2009)]. We discuss previous dc conductance measurements of quantum point contacts,
