  2. Photocurrent - Wikipedia

    en.wikipedia.org/wiki/Photocurrent

    The highest (maximum) value of the photo-current is called saturation current. The value of retarding potential at which photo-current becomes zero is called cut-off voltage or stopping potential for the given frequency of the incident ray.

  3. Saturation current - Wikipedia

    en.wikipedia.org/wiki/Saturation_current

    The saturation current (or scale current), more accurately the reverse saturation current, is the part of the reverse current in a semiconductor diode caused by diffusion of minority carriers from the neutral regions to the depletion region. This current is almost independent of the reverse voltage.

  4. Photoelectric effect - Wikipedia

    en.wikipedia.org/wiki/Photoelectric_effect

    When no current is observed through the tube, the negative voltage has reached the value that is high enough to slow down and stop the most energetic photoelectrons of kinetic energy K max. This value of the retarding voltage is called the stopping potential or cut off potential V o. [13]

  5. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    The effect of reverse saturation current on the I-V curve of a crystalline silicon solar cell are shown in the figure to the right. Physically, reverse saturation current is a measure of the "leakage" of carriers across the p–n junction in reverse bias.

  6. Langmuir probe - Wikipedia

    en.wikipedia.org/wiki/Langmuir_probe

    The bias voltage is chosen to be a few times the electron temperature so that the negative electrode draws the ion saturation current, which, like the floating potential, is directly measured. A common rule of thumb for this voltage bias is 3/e times the expected electron temperature.

    The American housing market has been a difficult one for many over the last several years, with high interest rates and soaring prices preventing many Americans from buying a new home. As such ...

  8. Space charge - Wikipedia

    en.wikipedia.org/wiki/Space_charge

    The slowing carriers also increases the space charge density and resulting potential. In addition, the potential developed by the space charge can reduce the number of carriers emitted. [16] When the space charge limits the current, the random arrivals of the carriers are smoothed out; the reduced variation results in less shot noise. [15]
