Abstract
 Now electron technology Unceasingly develops, semiconductor science and technology already becomes one of the most important science and technology in the modern times. PN junction is considered to be the core of great majority semiconductor devices, also, be caught the general public attention and be taken seriously. This text is to explain and discuss the forms and characteristic of      PN-junction. Certainly PN-junction forms the fundamental element of the semiconductor device, among them, the simplest crystal diode is made of PN junction . Therefore, studying the characteristic of PN-junction is to discuss the characteristic of crystal diode in fact. This text passes through the studying to crystal diode to expound on One-way conductivity.Breakdown of Characteristic capacitance characteristics, Temperature characteristics and so on of PN junction
Keywords: Semiconductor  Drift Movement  Proliferation  Free carrier  The forms of PN-junction
