Abstract:
|
We present experimental results for the ground-state electrochemical potentials of a few electron semiconductor artificial molecule made by vertically coupling two quantum dots, in the intermediate-coupling regime, in perpendicular and parallel magnetic fields up to B∼ 5 T. We perform a quantitative analysis based on local-spin density functional theory. The agreement between theoretical and experimental results is good, and the phase transitions are well reproduced. |
