Recently, we suggested an unconventional approach (the so-called Internal-Field-Guarded-Active-Region Design “IFGARD”) for the elimination of the quantum-confined Stark effect in polar semiconductor heterostructures. The IFGARD-based suppression

Quantum light sources exhibiting one- and two-photon emission are the key requirement for quantum cryptography ultimately leading to truly secure data transmission [1]. Physical realization can be obtained by parametric down-conversion [2], atomic [3

Although semiconductor excitons consist of a fermionic subsystem (electron and hole), they carry an integer net spin similar to Cooper-electron-pairs. While the latter cause superconductivity by forming a Bose-Einstein-condensate, excitonic condensat

Electronic properties of quantum dots are reviewed based on eight-band k⋅ p theory. We will focus on the following interrelated subjects: First the role of crystallographic symmetry is evaluated. This includes the symmetry of the lattice of the sub

The built-in dipole moments of excitonic and multiexcitonic complexes of GaN/AlN quantum dots (charged and uncharged excitons and biexcitons) are investigated in detail, both experimentally and theoretically. The calculations are done with Hartree-Fo

We present a combined experimental and theoretical study of two-photon emission from the biexciton cascade in single GaN quantum dots. By changing the biexciton binding energy, pump power, and temperature, the balance between the one- and two-photon

Coupling of acoustic phonons to excitons in single wurtzite-type GaN/AlN quantum dots is investigated in detail by cathodoluminescence experiments and compared to theory. Numerical simulations of the coupling in the framework of the independent Boson
