WebMar 20, 2010 · A high photoconductivity gain suggests that WO3 nanowires can be used as the sensing element for UV photodetectors. Measurements under UV light in vacuum show that the adsorption and desorption of oxygen molecules on the surface of the WO3 nanowire can significantly influence its photoelectrical properties. The WO3 nanowires have … WebAug 27, 2024 · The high IQE observed in the photoconductive response at −2 V is attributed to a high photoconductive gain of more than 40. This assumption was confirmed by mixed conduction behavior observed in a …
Photoconductivity is an optical and electrical phenomenon in which a material becomes more electrically conductive due to the absorption of electromagnetic radiation such as visible light, ultraviolet light, infrared light, or gamma radiation. When light is absorbed by a material such as a semiconductor, … See more When a photoconductive material is connected as part of a circuit, it functions as a resistor whose resistance depends on the light intensity. In this context, the material is called a photoresistor (also called light … See more In 2016 it was demonstrated that in some photoconductive material a magnetic order can exist. One prominent example is CH3NH3(Mn:Pb)I3. In this material a light induced … See more • Photodiode • Photoresistor (LDR) • Photocurrent See more Sensitization is an important engineering procedure to amplify the response of photoconductive materials.

WebNov 9, 2024 · This ultra-high photoconductivity gain is mainly due to the contribution of the sustained photoconductivity effect to the photocurrent. The trap centers on the surface of the 2D material to capture the photogenerated carriers and to help form additional electron transport channels (Fig. 4d). Compared with photoconductive detectors based on bulk ... WebOrganic single-crystalline semiconductors show great potential in high-performance photodetectors. However, they suffer from persistent photoconductivity (PPC) due to the charge trapping, which has severely hindered high-speed imaging applications. Here, a universal strategy of solving the PPC by in …
WebIn particular, the photo-generated electrons are trapped in CdS, while the photo-generated holes circulate in the external circuit, leading to a high photoconductivity gain. Motivated by these, we constructed a device that exhibits a photoresponsivity of ∼4.7 A W −1 , a response/recovery time of 13.7/15.8 ms, and a detectivity of 3.4 × 10 ...
