Due to the influence of the "inter electrode capacitance" of the PN junction,
Before use, crystal diodes must undergo positive and negative electrode identification and quality testing.
As mentioned earlier, the conductivity of impurity semiconductors can be greatly improved,
Two ions with different charged properties in the space charge region can establish an internal electric field within the space charge region.
The positive and negative ions that form a space charge region are also known as space charges.
Apply reverse voltage on both sides of the P-N junction.
