Discovery of Ionic Impact Ionization (I3) in Perovskites Triggered by a Single Photon

TL;DR: In this article, a room temperature intrinsic amplification process in methylammonium lead iodide perovskite (MAPbI3) was proposed, which can be triggered by a few photons, down to a single photon.
Proceedings ArticleDOI

Growth and characterization of ZnO nanostructures for UV sensor applications

TL;DR: The critical technologies being developed include ZnO nanostructures with wide band gap for UV detection for a variety of threat warning applications as mentioned in this paper, and the experimental results on the structural, electrical and optical properties of ZNO nanowire for UV detectors.
Proceedings ArticleDOI

Piezopotential tuned single ZnO micro-/nanowire photodetector

TL;DR: In this paper, the authors demonstrate the piezoelectric effect on the responsivity of a metal-semiconductor-metal ZnO micro-/nanowire photodetector.
Journal ArticleDOI

Deciphering facial movements.

TL;DR: An integrated system for the decoding of surface strains on the face and for predicting facial kinematics is reported, consisting of a low-cost wearable piezoelectric device for strain sensing, 3D-DIC for calibration and for guiding device placement, multiphysics modelling for processing the data, and an algorithm for the real-time classification of the piez Zoelectric signals.
