The devices, which operate on a heterojunction-gated (HG) structure, demonstrate high responsivity and detectivity while maintaining a simplified fabrication process. This approach avoids the ...

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 ...

This product training module provides an overview of optical sensor applications, technology and ROHM’s product offerings. It also introduces ROHM’s IR LED and IR phototransistors including its ...

Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure shows an infrared ...

The applications of eye-tracking devices are endless, which is why we always get excited to see new techniques in measuring the absolute position of the human eye. Cornell students [Michael and John] ...

A recent study published in Advanced Electronic Materials introduces a self-aligned gate architecture for carbon nanotube (CNT)-based phototransistors designed for ...
