Photoemission From A Two Electron Quantum Dot
Abstract
We consider photoemission from a twoelectron quantum dot and find analytic expression for the crosssection. We show that the emission crosssection from the ground state as a function of magnetic field has sharp discontinuities corresponding to the singlettriplet transitions for low magnetic fields and the transitions between magic numbers (2J+1) for high magnetic field. We also find the corrections to the photoemission crosssection from a more realistic quantum dot having a finite thickness due to nonvanishing extent of electron wave function in the direction perpendicular to the plane in which 2D dot electrons are usually confined.
