摘要：

We show that the finite size of pixels employed in arrays of the type produced by IMARAD Imaging Systems Ltd. determines the performance of these devices in terms of energy resolution and efficiency. The geometrical considerations are similar to those discussed in the context of small pixels. Based on an understanding of this geometrical effect we show that the performance of the arrays may be optimized for particular device dimensions. In addition we also so that material grown by IMARAD Imaging Systems Ltd. by the modified horizontal Bridgman method is quite uniform and indeed well suited for the fabrication of imaging systems.
