我们研究了单个InP量子点嵌入GaAs中,使用微光致发光作为激发强度的函数。InP/GaAs点表现出II型能带对准,这导致载流子的空间分离。磁场对这些II型量子点的影响也通过显微光致发光测量进行了研究。(© 2004 WILEY-VCH Verlag GmbH & Co. KGaA,魏因海姆)
We investigated single InP quantum dots embedded in GaAs using micro-photoluminescence as a function of the excitation intensity. InP/GaAs dots exhibit a type-II band alignment, which leads to a spatial separation of the carriers. The effect of a magnetic field on these type-II quantum dots were also investigated through micro-photoluminescence measurements. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
