Effect of Mn on the low temperature growth of GaAs and GaMnAs
With the combined use of reflection high energy electron diffraction (RHEED) and scanning tunneling microscope, the growing surfaces of GaAs and GaMnAs were investigated. At the start of GaAs growth at low temperature [...]
How Does Semiconductor Wafer Technology?
Edit by PAM-XIAMEN
The development of silicon wafer can be attributed to the development of Moore’s law. Because the silicon wafer for semiconductor is round, so the semiconductor silicon wafer is also called “silicon wafer” or “wafer”. Wafer is the “substrate” [...]
