T-Gate Dimensions file (2D) - full deck

Gate dimensions can be set in this script. They are now set to "RegSizeGate". The two other options given, "ASYMSizeGate" and "MinSizeGate" can be accessed by removing the hashtags in front of their set commands. Although these two options are the only ones given, the gate can be arbitrarily resized by choosing appropriate values in the set commands. The AlGaN thickness can also be resized via the "set AlThick" command. It is now set to 0.025um.
