Why are the wafers provided by PAM-XIAMEN round? Because the manufacturing process determines that it is round. Take the production process of silicon wafers as an example: The purified high-purity polysilicon is spin-grown on a seed. After the polycrystalline silicon is melted, put it [...]

The growth of p-type GaAs nanowires (NWs) on GaAs (111) B substrates by metal-organic chemical vapor deposition (MOCVD) has been systematically investigated as a function of diethyl zinc (DEZn) flow. The growth rate of GaAs NWs was slightly improved by Zn-doping and kink is [...]
