摘要
We have presented a theoretical study on ground state binding energy of the hydrogenic donor in the Surface Quantum Well composed of vacuum/GaAs/Ga1-xAlxAs. The effects of image charges and dielectric screening function on the hydrogenic donor binding energy are analysed. The results indicate that both of them have inverse effects. These results are compared with the results of other potential profiles previously reported. © Penerbit Universiti Sains Malaysia, 2017.
