<p>based on the very limited amount of information from your message, I can recommend a few things:<\/p><\/p>\n

    \n
  1. Try default strain (need to specify reference material, for example, InP, or GaAs). Adding Strain to the MQW Layers – Ansys Optics<\/a><\/li>\n
  2. Try user defined valence band offsets (VBO). These can often be found in the literature as CBO to VBO ratio. Sometime these values are not accurate enough in the default material database (which is mostly based on interpolation). Understanding band offsets in heterostructures – Ansys Optics<\/a><\/li>\n
  3. Check that the band structure and wavefunctions look correct. Do you see the expected number of subbands (e.g. 1 or 2 in the CB)?<\/li>\n<\/ol>\n
