Abstract

In this paper, the effects of absorbed photons in pixel and strip arrays were analyzed using the Ramo theorem. In fact, absorbing a photon in an array induces a current in the cell that has absorbed the photon and in its neighboring cells. This effect originates from the fact that all cells in the array are fabricated in the same substrate. These currents would be computed using Ramo theorem's weighted fields and traces of induced electron and hole which are created in the device due to the absorbed photon.
