- 論文の詳細を見る
The spin-conserved single-electron transport between Zeeman sublevels is investigated in a few-electron quantum dot in the single-electron tunneling regime. The differential conductance or transconductance for the ground state shows Zeeman splitting (doublet structure) in a magnetic field when the total spin is raised by adding an electron, but shows no splitting when it is lowered. Although the characteristics of such transport do not depend solely on the actual spin degeneracy, the spin state can be identified by consecutively investigating the change of the spin from a known spin state. We also discuss Zeeman splitting when the electron-spin $g$-factor depends on electron number.
