在简要描述了双面制作工艺之后，我们给出了一个例子，表明通过将256个结的堆叠超导连接在一起，可以制作出相当大的本征约瑟夫森结阵列。这些堆叠中的每一个仅包含40个结，这防止了由加热引起的问题。我们提出了一个新的结构，我们已经开发出一个额外的电极可以制造在一个阵列的中间，通过稍微修改的双面过程中的详细讨论。使用这个中间电极，我们可以确定更多的信息，在堆栈内的物理过程比没有这样的电极是可能的。最后，我们将讨论太赫兹产生的IJs时，外部磁场施加垂直于宽度的结。
After a brief description of the double-sided fabrication process, we give an example to show that a quite large array of intrinsic Josephson junctions (IJJs) can be made by superconductively connecting 256 stacks of junctions together. Each of these stacks contains only 40 junctions which prevents problems causing by heating. We present a detailed discussion on a new structure we have developed in which an extra electrode can be fabricated in the middle of an array by a slight modification of the double-sided process. Using this middle electrode, we can determine further information on the physical processes inside the stack than is possible without such an electrode. Finally we shall discuss terahertz generation in IJJs when an external magnetic field is applied perpendicular to the width of the junctions.
