Semiconductor diode
semiconductor
Semiconductor material
Ge
Si
GaAs
Semiconductors are electrically neutral to the outside world
Intrinsic semiconductor
Definition: A pure semiconductor that is completely free of impurities and crystal defects
Features
Electron concentration = Hole concentration
Poor electrical conductivity
Low carrier concentration
As the temperature increases, the number of carriers increases
Intrinsic excitation: When the temperature of the semiconductor is T>0K, electrons break away from the covalent bond to form free electrons.
intrinsic carriers
Hole: A vacancy formed when an electron breaks away from a covalent bond and becomes a free electron
Free electrons: Valence electrons break covalent bonds and form freely moving electrons
impurity semiconductor
N-type semiconductor (N-Type)

indium
Features
electrically neutral
Not enough electrons to form covalent bonds, creating holes
PN junction(P-N) junction
Formation: The N-type impurity region is in close contact with a P-type impurity region, and a depletion region is generated at the junction.
Carrier diffusion movement: concentration difference
Many carriers (holes) in the P-type region diffuse to the N-type region
Diffusion of electrons (electrons) from the N-type region to the P-type region
drift motion
The trapped charged ions (P-type negative ions, N-type positive ions) form a self-constructed electric field, driving the minority carriers to move toward low potential.
Features
The direction of the internal electric field of the PN junction is from the N region to the P region.
Has one-way conductivity
The external voltage causes the current to flow from N to P, with high resistance and small current.
The external voltage causes the current to flow from P to N, with low resistance and large current.
Forward bias: The P terminal is connected to positive, the N terminal is connected to negative, the depletion layer becomes narrower, aggravates the diffusion movement, prevents drift movement, and the PN junction is turned on
Reverse bias: The N terminal is connected to the positive electrode, the P terminal is connected to the negative electrode, the internal electric field is strengthened, the depletion layer becomes wider, the drift current comes from the minority carrier, the current is very small, and the PN junction is cut off
Shockley's equation:
is the reverse saturation current
is the forward bias voltage applied to the diode
is the ideal factor, usually 1
