In thisstudy, the total refractive index (RI) changes of GaN / AlxGa1-xN Core-Shell quantum dots are calculated with a hydrogenic impurity. Our results show that the RI changes are considerably sensitive to the geometrical parameters of systems. The peak position of the total refractive index changes is greatly affected by changing of the geometrical size and presence of the hydrogenic impurity. The possibility of tuning the resonant energies by using the geometric core shell effect of the spatial confinement can be useful in the optoelectronic devices applications..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
