摘要：
In the present work,a nanoporous ZnO/n-Si structure has been proposed as a new type infrared photodetector.Triggered by one laser pulse with wavelength of 1064 nm,this structure exhibits a double-peak decay of transient photovoltage.Also,the time interval between these two peaks increases linearly with the increase of irradiated pulsed energy,indicating the promising application of this hetero-junction in photo-energy detection of infrared pulsed laser.A possible mechanism for this particular photoresponse has been discussed.
