1、avalanche breakdown semiconductor laser

2、What was known as avalanche breakdown occurred.

3、PN junction is the foundation of almost all the power devices. The avalanche breakdown voltage of PN junction determines the work voltage range of related power devices.

4、For maximum exceed noise ratio generated, circuit structure to match the equivalent circuit diagram of the solid-state noise diode in avalanche breakdown state has been designed.

5、In this paper, the area contact model of depletion layer width under avalanche breakdown in Si epitaxial wafer by a three-probe method is analysed. The theory accords with experimental results.

6、The simulation analysis indicates that with this structure the avalanche breakdown voltage of RF power transistors can be increased to be over 90% of that for an ideal parallel .
