“…26 In the case of ZnO, the single band isotropic mass approximation predicts the existence of the excitons bound to ionized donors. 25 Next, the presence of acceptors in the ZnO:N may induce the ionization of the shallow donors 27 as in the case of Li and Na doped ZnO.…”

We present results of magneto-optical measurements and theoretical analysis of shallow bound exciton complexes in bulk ZnO. Polarization and angular dependencies of magneto-photoluminescence spectra at 5 T suggest that the upper valence band has Γ7 symmetry. Nitrogen doping leads to the formation of an acceptor center that compensates shallow donors. This is confirmed by the observation of excitons bound to ionized donors in nitrogen doped ZnO. The strongest transition in the ZnO:N (I9 transition) is associated with a donor bound exciton. This conclusion is based on its thermalization behavior in temperature-dependent magneto-transmission measurements and is supported by comparison of the thermalization properties of the I9 and I4 emission lines in temperature-dependent magneto-photoluminescence investigations.

“…The stability of semiconductor trions has been predicted long ago [1,2]. However, their binding energies being extremely small in bulk materials, clear experimental evidences [3][4][5] of these exciton-electron bound states have been achieved recently only, due to the development of good semiconductor quantum wells, the reduction of dimensionality enhancing all binding energies.…”

The X − trion is essentially an electron bound to an exciton. However, due to the composite nature of the exciton, there is no way to write an exciton-electron interaction potential. We can overcome this difficulty by using a commutation technique similar to the one we introduced for excitons interacting with excitons, which allows to take exactly into account the close-to-boson character of the excitons. From it, we can obtain the X − trion creation operator in terms of exciton and electron. We can also derive the X − trion ladder diagram between an exciton and an electron.These are the basic tools for future works on many-body effects involving trions.PACS number : 71.35.-y Excitons and related phenomena 1

“…In spite of the large number of theoretical [1][2][3][4][5][6][7][8][9][10][11] and experimental [12][13][14][15][16][17][18][19][20][21][22][23] works published in recent years on the subject of charged excitons in quantum wells, only a very small number of them deals with positively charged excitons 4,6,10,14,16,18,19 . Different authors 4,18 used the diffusion Monte Carlo technique to calculate the dependence of the binding energy of the positively charged exciton on the well width at zero magnetic field.…”

Positively charged magnetoexcitons in a semiconductor quantum well

A variational calculation of the lower singlet and triplet states of positively charged excitons (trions) confined to a single quantum well and in the presence of a perpendicular magnetic field is presented. We study the dependence of the energy levels and of the binding energy on the well width and on the magnetic field strength. Our results are compared with the available experimental data and show a good qualitative and quantitative agreement. A singlet-triplet crossing is found which for a 200Å wide GaAs is predicted to occur for B= 15 T.
