Collectedcharged

Collectedcharged is a term that appears in some technical discourses as an informal compound noun to denote the net electric charge gathered by a device or electrode from an external source over a defined period. It is not widely standardized in scientific literature; more common phrases include "collected charge" and "charge collection."

In formal use, collectedcharged can be described by the relation Q_collected = ∫ I_collected(t) dt, where I_collected(t) is the current delivering charge to the electrode. For a constant current, Q_collected = I_collected × Δt. The rate of collection is the current, and the efficiency is often expressed as the ratio to the total generated or incident charge.

Applications include radiation detectors, semiconductor sensors, photovoltaic devices, and electrostatic precipitators. In detectors such as silicon diodes or photodiodes, the amount of collectedcharged determines the measurable signal. Factors that influence it include the depletion region, carrier trapping, recombination, leakage currents, and device geometry, as well as environmental conditions such as temperature and electric field.

Measurement is typically accomplished with charge-sensitive electronics that integrate current over time, or with devices that directly convert charge to voltage. The concept is closely related to charge collection efficiency and to parameters such as capacitance and noise in precision instrumentation. See also: collected charge, charge collection efficiency.
