概要

• 論文の詳細を見る

• A series of electric pulses is applied to virgin alternating-current thin film electroluminescent ZnS-based samples in order to investigate the behaviour of the excitation efficiency within the first drive periods. One observes a decrease of the excitation efficiency from the first pulse on. The steady state values of the transferred charge and the excitation efficiency are attained after about ten drive periods. These transient measurements permit one to investigate the establishment of the bulk space charge in the ZnS layer in this kind of devices.
