Low-temperature growth of GaAs on Si used for ultrafast photoconductive switches
GaAs was grown directly on silicon by molecular beam epitaxy (MBE) at low substrate temperature(∼250°C). Both the silicon wafer cleaning and the GaAs film growth processes were done attemperatures lower than the Si-Al eutectic temperature to enable monolithic integration of low-temperature-GaAs photoconductive switches with finished Si-CMOS circuits. The film surfaces show less [...]

As the basis for making photovoltaic cells and integrated circuits, silicon wafer cleaning is very important. The effect of cleaning directly affects the final performance, efficiency and stability of photovoltaic cells and integrated circuits. Cleaning the silicon wafer not only removes impurities on the [...]
