Engineering Physics Annotation << Back DENSITY FUNCTIONAL THEORY OF TWO-DIMENSIONAL ELECTRON-HOLE COMPLEXES A.А. VASILCHENKO The energy of the two-dimensional electron-hole complex is calculated in theframework of density functional theory. It is shown that the energy of the direct two-dimensional exciton without the exchange-correlation interaction is very different from the exact value. We found that the number of particles in the complex decreases with increasing interlayer distance for indirect electron-hole complexes in strong magnetic field. Key words: exciton, the electron-hole complex, density functional theory. Contacts: E-mail: a_vas2002@mail.ru Pp. 3-5.
