Carrier transport in signal-processing-in-the-element (SPRITE) detectors is an important phenomenon because it determines properties such as the responsivity and the modulation transfer function (MTF). The previous literature has presented approximate solutions to the transport problem that neglect boundary effects, which have long been thought to play a major role in SPRITE behavior. We present a new solution to the problem through the use of modal analysis. This method intrinsically includes boundary conditions and thus is more complete than the previous analysis. Furthermore we use this solution to derive expressions for the MTF. The effects of the boundary conditions on the MTF are studied to determine their optimum values.
在信号处理元件（SPRITE）探测器中的载流子输运是一个重要现象，因为它决定了诸如响应度和调制传递函数（MTF）等特性。先前的文献提出了忽略边界效应的输运问题近似解，而长期以来人们一直认为边界效应在SPRITE行为中起主要作用。我们通过模态分析提出了该问题的新解。此方法本质上包含了边界条件，因此比先前的分析更完整。此外，我们用这个解来推导MTF的表达式。研究了边界条件对MTF的影响以确定其最佳值。
