| 中文摘要 | the hamiltonian of wurtzite quantum rods with an ellipsoidal boundary under electric field is given after a coordinate transformation. the electronic structure and optical properties are studied in the framework of the effective-mass envelope-function theory. the quantum-confined stark effect is illustrated by studying the change of the electronic structures under electric field. the transition probabilities between the electron and hole states decrease sharply with the increase of the electric field. the polarization factor increases with the increase of the electric field. effects of the electric field and the shape of the rods on the exciton effect are also investigated. the exciton binding energy decreases with the increase of both the electric field and the aspect ratio. in the end, considering the exciton binding energy, we calculated the band gap variation of size- and shape-controlled colloidal cdse quantum rods, which is in good agreement with experimental results. |
