Since the nonlinear response of the nuclear field is sensitive to the electron g factor and correlation time of a coupled electron-nuclear spin system, the resultant Overhauser shift is their good measure for individual quantum dots. This method provides a simple and convenient alternative to the standard photon cross-correlation method.American Institute of Physics2008engjournal articleVoRhttp://hdl.handle.net/2115/49865https://doi.org/10.1063/1.28396150003-6951AA00543431Applied Physics Letters924041915-1041915-3https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/49865/1/GetPDFServlet.pdfapplication/pdf567.68 KB2008
