InP Single crystal substrate
InP Single crystal material is one of the most important compound semiconductor materials, which is the key material in optical fiber communication technology. Based on InP, laser diode (LD), light-emitting diode (LED) and photodetector realize the functions of information transmitting, transmitting, amplifying and receiving in optical fiber communication. InP is also very suitable for high frequency devices, such as high electron mobility transistor (HEMT) and heterojunction bipolar transistor (HBT). Due to its advantages, InP has been widely used in many high-tech fields, such as optical fiber communication, microwave, millimeter wave, anti radiation solar cell, heterocrystal tube and so on
