چکیده

The piezo-phototronic effect is about the use of the inner crystal piezoelectric potential to tune/control charge carrier generation, separation, transport and/or recombination in optoelectronic devices. In this paper, a theoretical model for describing the characteristics of a metal-nanowire-metal structured piezo-phototronic photodetector is constructed. Numerical simulations fit well to the experimental results of a CdS and ZnO nanowire based visible and UV detector, respectively.

Enhancing sensitivity of a single ZnO micro-/nanowire photodetector by piezo-phototronic effect.

We demonstrate the piezoelectric effect on the responsivity of a metal-semiconductor-metal ZnO micro-/nanowire photodetector. The responsivity of the photodetector is respectively enhanced by 530%, 190%, 9%, and 15% upon 4.1 pW, 120.0 pW, 4.1 nW, and 180.4 nW UV light illumination onto the wire by introducing a -0.36% compressive strain in the wire, which effectively tuned the Schottky barrier ...

In this work, we present a facile, low-cost, and effective approach to fabricate the UV photodetector with a CuI/ZnO double-shell nanostructure which was grown on common copper microwire. The enhanced performances of Cu/CuI/ZnO core/double-shell microwire photodetector resulted from the formation of heterojunction. Benefiting from the piezo-phototronic effect, the presentation of piezocharges c...

Piezo-phototronic effect enhanced visible/UV photodetector of a carbon-fiber/ZnO-CdS double-shell microwire.

A branched ZnO-CdS double-shell NW array on the surface of a carbon fiber (CF/ZnO-CdS) was successfully synthesized via a facile two-step hydrothermal method. Based on a single CF/ZnO-CdS wire on a polymer substrate, a flexible photodetector was fabricated, which exhibited ultrahigh photon responsivity under illuminations of blue light (1.11 × 10(5) A/W, 8.99 × 10(-8) W/cm(2), 480 nm), green li...
