Abstract
Some results of the numerical calculation of the electron ground state energy and electron density in tunnel-coupled InAs/GaAs quantum dots composing a simple cubic superlattice are presented. The calculation is performed within the modified effective mass method taking into account the microscopic (atomic) structure of individual quantum dots without taking spin-orbit coupling and strain effects into account. The dependence of the electron binding energy on radius R of quantum dots is studied. The electron binding energy is demonstrated to be proportional to R3 in the region of R < 27 Å.
