Figure 4 shows the top view of the SAPIN and a simplified cross-section drawing of the SAPIN diode. 1 As a normal PIN diode, the device has a p+ anode, undoped i-region, and an n+ cathode connection.

Understanding the roles of cathode and anode is an important topic in chemistry. These electrodes facilitate essential reactions in both electrochemical and electrolytic cells. By knowing their ...
