我们报告测量的转换率从J=2激子到J=1激子,以及从右手J=1激子到左手J=1激子的转换,和测量的固有辐射寿命的J=1激子,在非常高质量的GaAs量子威尔斯。由于实验是在非常低的温度下进行的,并且具有共振激发,因此不存在能量弛豫的影响。
We report measurements of the rates of conversion from J=2 excitons to J=1 excitons, as well as conversion from right-handed J=1 excitons to left-handed J=1 excitons, and measurement of the intrinsic radiative lifetime of J=1 excitons, in very-high-quality GaAs quantum wells. Since the experiments are performed at very low temperature and with resonant excitation, the effects of energy relaxation are absent.
