As detailed in the previous reports, the necessary current densities 60 Asq cm, linear current densities 3 mAmm and stability much much more 2 days to meet the contract goals at least theoretically have been achieved. The next step is to fabricate three terminal devices to demonstrate the remaining contract goal - a one GHz current gain cutoff frequency f sub t. During this period the design of the three terminal devices was completed and the mask set was received at the end of the period. RF modulation at one GHz was also demonstrated as high as 2 GHz with an incremental gain in s sub 21 of 0.5 dB.
