Abstract
The present invention relates to a photo-response detector, in particular to a ferroelectric field modulated positive and negative photo-response detector, a preparation method and application thereof. The ferroelectric field modulated positive and negative photo-response detector includes a substrate, a gate electrode, a ferroelectric layer, a low-dimensional semiconductor and a source-drain electrode. A pair of gate electrodes are provided and fixedly arranged on the substrate at intervals. The ferroelectric layer is fixedly arranged on the substrate and completely covers the gate electrode. The low-dimensional semiconductor is fixedly arranged on the ferroelectric layer. The source-drain electrode includes a source electrode and a drain electrode separately arranged on two sides of the low-dimensional semiconductor and fixedly arranged on the ferroelectric layer.
