We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi,

Thanks for your questions:

  • The paritioning in CHARGE:MQW can be edited. To do this go to advanced settings (under CHARGE:MQW:Advanced), and enable the override partition table option. Please take note of the displayed warning regarding number of quantum wells per partition. I agree that the partitions should be defined/populated at barriers, so hopefully this can allow you to make the needed correction.
  • Regarding the auto-population, this can not be disabled in CHARGE and is automatically read from the MQW domain. 
  • For the thickness defined and what’s shown in this table, I notice the same behavior exists in our published example here, where the outer barriers are shown as 0.02 micron and not the thickness manually defined. I think this value may not be important as these are the most outer layers, and may be considered infinite barrier. I will double check this with our team internally, and let you know if I have any updates. Do you see such discrepancy in other layers as well (aside from the first and last layer in the table)?

Thanks
