Hi,
I am trying to convert a monolayer black phosporus double gate structure by using device from bulk option. But after trying to convert the structure a error message appears which is as below. Please help me about this problem . I am using QuantumATK 2019.12 SP-1. I also attached the py file of the structure

I think it includes a bug to convert device from bulk. Because it works surface from bulk without doping state.
However I found the solution to convert the device from your bulk model. Can you remove all doping and spatial region in the bulk? Then convert device from bulk. It will work. After that, split into the electrode and central region. In the central region, add the doping and spatial region. At last, convert device from bulk. If you have in trouble, let me know about it.

You have discovered a bug in the Q-2019.12 version of QuantumATK that has been fixed for the upcoming R-2020.09 release.

As a workaround, you can select the option 'Set up electrode cross-section as a supercell' in the 'Device from Bulk' widget as indicated in the attached screenshot.

Hi Pieter,

The error appears wen i clicked into the device from bulk widget. Now the problem is severe that i cannot even open the widget.

You can create your device configuration by pasting the following code snippet at the bottom of the script that defines your bulk configuration:
Code
from NL.CommonConcepts.Configurations.DeviceFromBulk import deviceFromBulk, findBothElectrodeLengths
device_configuration = deviceFromBulk(
    electrode_lengths=findBothElectrodeLengths(bulk_configuration) * Angstrom,
    bulk_configuration=bulk_configuration,
    enable_minimal_electrodes=True,
    enable_transverse_electrode_repetitions=False,
)
The issue in Nanolab will be resolved in the R-2020.09 release scheduled for September 8.
