Abstract: In this letter, the channel length effect, combined with the photoelectric field effect of organic phototransistors, has been investigated for the first time. Reducing the channel length and ...

Abstract: An a-IGZO thin-film phototransistor incorporating graphene absorption layer was proposed to enhance the responsivity and sensitivity simultaneously for photodetection from ultraviolet to ...

Researchers have developed a soft artificial retina that helped blind mice respond to near-infrared light, a type of light ...

Researchers in South Korea have developed an ultra-thin implantable artificial retina that converts near-infrared light into electrical signals to stimulate surviving retinal neurons, potentially ...

The retina, the thin layer of tissue at the back of the eye, is made up of photoreceptor cells that convert visible light ...

Une photodiode est un composant semi-conducteur ayant la capacité de détecter un rayonnement du domaine optique et de le transformer en signal électrique. Pour avoir une meilleure efficacité quantique ...

Neurophos, an AI chip company backed by Bill Gates's Gates Frontier Fund, has announced that it is developing an optical processing unit (OPU) that is said to deliver 10 times the performance of ...

A single phototransistor mimics retinal bipolar cell function while detecting visible and infrared light, enabling low-power image processing through programmable ON and OFF photoresponses. (Nanowerk ...
