-**New feature**: a combined temperature-voltage sweep can be done using the keyword ''​Temperature-Voltage''​ in the field ''<​SweepType>''​ of ''<​SweepParameters>''​ (see the example of code below). In this case, the simulation can be parallelized. ''<​Threads>''​ defines the number of parallel threads. Its optimal value should be the number of CPU cores available (if the available memory is sufficient). Within each parallel temperature sweep, a serial voltage sweep is performed.

-    <​Threads>​12</​Threads>​ <!-- Parallelization for Temperature-Voltage sweep --> 
-</​SweepParameters>​ 
-</​code>​ 
-Note that for such voltage-temperature sweep, ''<​Maximum_Number_of_Threads>''​ in ''<​Simulation_Parameter>''​ should be set to ''​1''​. (A combined parallelization will result in lower performances.)

-At the end of the simulation, current and gain maps can be displayed. 
-''​Gain_map.fld''​ gives the maximum gain at each (voltage,​temperature) point. 
-''​Max_Gain_frequency.fld''​ gives the map of the corresponding photon energy for which the gain is maximum.
