Dear Supporter:
i have finished IV  characteristics calculation, and now I want to calculate the device of density if states Vds AV at BV Vgs,   
but when i used Analysis from file ---->select the iv characteristic hdf5 file, and shows below, there is no option let me select the specific Vds at Vgs .
so i am wondering how to continue to calculation the Device density of states based on already ready iv characteristic hdf5 file.
thanks very much if you could give me some hints.

If you are using the IVCharacteristics study object, you may also use it to calculate analysis objects, as discussed in the manual, and

You also extract a particular device configuration for a given gate and bias voltage, and then do analysis from file in a usual way.

Code: [Select]
iv_characteristics=nlread('device-ivcharacteristics.hdf5', IVCharacteristics)[-1]

device_configuration=iv_characteristics.configuration(1.0*Volt, 0.0*Volt)

nlsave('device-0.0-bias.hdf5', device_configuration)

where gate_source_voltage=1 .0*Volt and drain_source_voltage=0.0*Volt
