The Electron–Phonon Interaction in a Quantum Dot
The Electron–Phonon Interaction in a Quantum Dot
Arrays of semiconductor quantum dots have the potential for high–power lasers and for the generation of ultra-short pulses. Theoretical concerns include the description of the electron–hole interaction in a quantum dot, how electrons and holes recombine radiatively and non-radiatively, and how excited electrons and holes relax their energies. This chapter focuses on the electron–phonon interaction in the isotropic material that forms a spherical quantum dot. It includes: anharmonic coupling; the Huang–Rhys factor; the configuration-coordinate diagram; the exciton; polar and deformation interactions; and a simple model.
Keywords: electrons, phonons, quantum dot, semiconductor, Huang–Rhys, factor
