ABSTRACT
The tunneling current through a quantum dot array (QDA) is studied theoretically. Strong electron correlation effect is taken into account in the QDA in which the quantum dots provide a strong three-dimensional confinement effect. A mixed Hubbard and Anderson model is used to simulate the system. It is found that Coulomb charging splits the band resulting from interdot coupling into two subbands. The tunneling current is thus influenced significantly by both Coulomb charging and interdot coupling. © 2001 American Institute of Physics.

    In contrast to group-III arsenide-based quantum dots, group-III nitride-based quantum dots are much smaller in size and have less conduction band offset. For this reason, it is important to take into account the electron-hole Coulomb interaction in which the spherical quantum dot is substituted...

    A mechanism of nonradiative recombination of nonequilibrium carriers in semiconductor quantum dots (QDs) is suggested and discussed. Recombination of an electron-hole pair localized in a QD occurs via Coulomb (Auger) interaction with carriers in the barrier region. It is shown that the...
