Photoelectrochemical self-powered photodetector based on 2D liquid-exfoliated bismuth nanosheets: with novel structures for portability and flexibility

A high-performance and self-powered polarization-sensitive photoelectrochemical-type Bi2O2Te photodetector based on a quasi-solid-state gel electrolyte

“…4f, and the detailed performance parameters are summarized in Table 1. [28][29][30][31][32][33][34][35][36] Impressively, the Bi (Ox). As a result, the photocurrent can be detected at zero bias by using a semiconductor parameter analyzer.…”

Two-Dimensional Metal Nanostructures: From Theoretical Understanding to Experiment

“…Nanosheets of metals other than those discussed in the previous subsections are much less common because of the lack of stability in a typical chemical synthesis. Still, there have been various reports in recent years on the syntheses of 2D nanostructures of a range of metal elements, including Mg, Al, , Ti, − Cr, Fe, − Co, − Ni, − Cu, ,− Zn, − Ga, Ru, − Sn, and Bi. − Conventional liquid-phase synthesis, the solvothermal method, the template-mediated method, and electrochemical reduction have been developed along with some other unique approaches, such as topotactic transformation and exfoliation. A molten-salt-assisted synthesis was conducted for the preparation of Bi or Sb nanosheets .…”

Oxygen Vacancies Modified Bi4O5I2 for Sensitive and Stable Photoelectrochemical‐Type Photodetection

“…Photoelectrochemical (PEC)-type photodetectors have been regarded as a kind of promising functional device in the field of imaging, optical communication, and energy conversion, owing to the various merits such as facile fabrication process, cost-effectiveness, and superior device performance. [1][2][3][4][5] PECtype devices combine the advantages of electrochemical and optical devices allowing for self-power via the redox chemical reactions between the working and counter electrode under the light illumination. [6,7] Meanwhile, the PEC-type photodetectors exhibit fascinating photoresponse.…”
