I am now having an issue understanding how to create the p-i-n junction energy band diagram profile. I have attached an .mph file with the geometry and the doping. I have the p side metal contact at -5 V and the n side metal contact at 0 V (reverse bias). However, ...

ThePN-junction diodeis made up of two adjacent parts of two semiconductor materials like p-type and n-type. These materials aresemiconductorslike Si (silicon) or Ge (germanium), including atomic impurities. Here the type of semiconductor can be determined by the kind of impurity there. The pr...
The above symbol represents thediodethat allows the current to pass only in one direction and blocks the current to flow in the opposite direction. The types of the diode are: Light Emitting Diode Zener diode Photodiode PN junction diode Laser diode Transistor Use Circuit Symbols Now The functio...
This diode operation mainly depends on the range of doping in the PN junction. For a little reverse bias voltage, the depletion region is extremely thin & the electric field is extremely high. It permits the electrons to flow from the valence band to the conduction band. ...
In addition, these resistors are low responsive to phototransistors & photodiodes. A photo-diode is a PN-junction semiconductor device, used to change the light to electricity, while a photocell is a passive device and it doesn’t include a PN junction but is used to convert light to electr...
a broad range of wavelengths from the near UV, through the visible, and into the near IR part of the spectrum. For a given light source illumination level, the output of a phototransistor is defined by the area of the exposed collector-base junction and the dc current gain of the ...
