What if ultrafast pulses of light could operate computers at speeds a million times faster than today's best processors? A team of scientists, including researchers from the University of Arizona, are ...

Particular interest has been on semiconducting materials, such as molybdenum disulfide (MoS2), an abundant material in nature, which exhibits the unique physical, optical and electrical properties ...

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 ...

No one likes a flickering light source, but lighting is often dependent on the quality of a building’s main AC power. Light intensity has a close relation to the supply voltage, but bulb type plays a ...

A designer who uses a phototransistor to convert a modulated optical signal to an electrical signal frequently encounters problems when high-intensity background light saturates the phototransistor.

Researchers in Taiwan say they have created a new chlorophyll-coated graphene phototransistor that is much more sensitive to light than devices made of pure graphene. The researchers believe that the ...

A digital camera has an array of sensors that captures light reflected or transmitted onto it. This build is something closer to a reverse camera – a single sensor that makes images on a matrix of ...

This applications note presents some basic facts about phototransistors including its different architectures commonly used in the industry. It discusses its operation and how things work inside these ...

Inspired by mammals' eyes, electrical engineers have created the fastest, most responsive flexible silicon phototransistor ever made. Inspired by mammals' eyes, University of Wisconsin-Madison ...

Researchers from the Department of Physics in the College of Science and the James C. Wyant College of Optical Sciences, all at the University of Arizona, have demonstrated a way to manipulate ...

MALVERN, Pa., Feb. 25, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of phototransistor optocouplers that combine a high and linear current transfer ...
