    Investigation of Polarisation in CdTe using TCT
    (IOP Science, 2016-04-15) Prokopovich, DA; Ruat, M; Boardman, DA; Reinhard, MI
    The polarisation effect in CdTe:Cl has been studied using the Transient Current Technique (TCT) in order to quantitatively evaluate the subsequent changes in the charge transport properties as well as the electric field distribution in the sensor volume. The electric field is calculated from TCT pulses using the Schockley-Ramo theorem. The mobility of the charge carriers as well as their average drift velocity in the CdTe material are determined using the TCT pulse width. Infrared illumination demonstrated a temporary restoration of the electric field. However after a few minutes the polarization effect is resumed, even under constant IR illumination. © 2014, IOP Publishing Ltd and Sissa Medialab srl.
