摘要：

We fabricated quantum dots arrays on a GaAs/Al0.3Ga0.7As quantum well by using electron beam lithography and chemical wet etching, and studied their transport properties. We especially focused on geometrical dependence of conductance through quantum dots arrays. We measured I-V characteristics of samples with two different geometrical forms, which consisted of ten quantum dots in straight and zigzag forms. We also investigated a difference in transport properties between two types of samples, which are quantum dots arrays with and without Al-g ate on top of the samples.
