I synthesized a nanostructure, ofcourse its dimensions were less than 100 nm. I doped a metal in the semiconductor nanostructure. Then Photoluminescence spectroscopy was carried out at 10 to 100 Kelvin with a step of 10 Kelvin and also at higher temerature. I found some of the peaks which were never reported before. So, I decided to calculate the electron transitions in the nanostructure which might be behaving like quantum well due to its dimensions. So, please let me know, is there any tool, software, mathematical model etc. which can be applied to calculate the band transition of the Doped semiconductor nanostructure, which might be behaving like quantum well?
