photocurrent

The resulting current I is called the generation photocurrent.

If the electric field is strong enough, electrons can be moved and collected to produce a photocurrent.

For example, at the level of the retinal cones, the response might be in photocurrent.

The photocurrent of just one photon can be registered with these electronics devices.

The overlap between these two spectra determines the maximum possible photocurrent.

Photocurrent caused by ultraviolet and x-ray radiation may belong to this category as well.

The effect of the laser on the active transistor region is to generate a localized photocurrent.

Consequently, due to the accumulation of charges, a potential V and a photocurrent I appear.

The photocurrent may occur as a result of the photoelectric, photoemissive, or photovoltaic effect.

Excitons generated within this length close to an acceptor would contribute to the photocurrent.

This method increases the photocurrent, but the thin film SC would then have poor material quality.

This photocurrent is a temporary effect and only occurs during the time that the laser is stimulating the target region.

The photocurrent still contains shot noise.

The dark current includes photocurrent generated by background radiation and the saturation current of the semiconductor junction.

These devices can control relatively high current (a few mA) and have a quasilinear dependence of photocurrent on the light intensity at a constant voltage.

Thus holes move toward the anode, and electrons toward the cathode, and a photocurrent is produced.

For a given spectral distribution, the photocurrent is linearly proportional to the illuminance (and to the irradiance).

The creation of this photocurrent alters the transistor operating parameters, which may be observed as a change in function of the device.

Unlike bipolar transistors, FETs do not inherently amplify a photocurrent.

When used in zero bias or photovoltaic mode, the flow of photocurrent out of the device is restricted and a voltage builds up.

The reverse bias induces only a small amount of current (known as saturation or dark current) along its direction while the photocurrent remains virtually the same.

In that case, space-charge limited photocurrent (SCLP) hampers device performance.

There are constant reports of efficiency numbers for photovoltaic materials that are generated without separating excitons to produce a useable photocurrent.
