After the ingot production is finished the impurities are present in the bulk crystals. 6"Ø×625±25µm, The high-frequency performance of GaAs proves that it is a better alternative to silicon in some applications. A researcher requested a quote for epitaxy ready (100) undoped (semi-insulating) GaAs 2” wafers with one side polished. To meet this high speed requirement for switching we would suggest using Semi-Insulating GaAs wafers with Ro>1E7 Ohm-cm to prevent high current induction in the circuit.  For integrated circuits (rather than individual transistors) it is best to work with (100) orientation {rather than  (111) or (110). high temperatures.
