Etymology

Origin of photocurrent

First recorded in 1910–15; photo- + current

Example Sentences

Professor Patané, who led the sensor development, explains what makes the results stand out: "This work combines for the first time the generation of femtosecond UV-C laser pulses with their fast detection by 2D semiconductors. Unexpectedly, the new sensors exhibit a linear to super-linear photocurrent response to pulse energy, a highly desirable property, laying the foundation for UV-C-based photonics operating on femtosecond timescales over a wide range of pulse energies and repetition rates."

From Science Daily

Thirdly, the ZnO nanoparticles are photoresponsive and generate a photocurrent when exposed to pulsed UV light and a constant voltage.

From Science Daily

This photocurrent mimics the responses transmitted by synapsis in the human brain, enabling the device to interpret and process biological information received from optical sensors.

From Science Daily

In their experiments, Gabor and his colleagues used a microscopy method that employs a uniform rotating magnetic field to image photocurrent streamlines through ultrathin devices made of a layer of platinum on yttrium iron garnet, or YIG.

From Science Daily

To generate a photocurrent in a desired direction, the researchers directed a laser beam on YIG, with the laser serving as a local heat source.
