The pn junction
WebbP-N 접합 (p–n junction)은 현대 전자공학에서 유용하게 사용할 수 있는 성질을 가지고 있다. P형 반도체 나 N형 반도체 나 모두 전도율 이 좋다. 하지만, 이 둘 사이의 접합면은 그렇지 않다. 이 전도율이 떨어지는 접합면을 공핍영역 (depletion zone)이라고 하며, P형 ... WebbCHAPTER THREE. PN JUNCTION DIODES 3.1 Introduction When a p-type semiconductor material is suitably joined to n-type semiconductor, the contact surface is called a p-n junction. The p-n junction is also called as semiconductor diode. Figure 3.1 shows the schematic diagram (a) and block diagram (b) of the PN-junction. A PN-junction is …
