我们目前的测量单InGaN量子点的光致发光衰减动力学。重组的特点是由一个单一的指数衰减,相反,在二维润湿层中看到的非指数重组动力学。在4 ~ 60 K的温度范围内,单点的寿命随温度的升高而降低。(C)2003年,美国物理学会。
We present measurements of photoluminescence decay dynamics for single InGaN quantum dots. The recombination is shown to be characterized by a single exponential decay, in contrast to the nonexponential recombination dynamics seen in the two-dimensional wetting layer. The lifetimes of single dots in the temperature range 4 to 60 K decrease with increasing temperature. (C) 2003 American Institute of Physics.
