• Resumen

  • This chapter is devoted to the analysis of the key properties of low-dimensional structures, comprising quantum wells, wires, and dots (i.e., 2D, 1D, and 0D quantum structures). These properties are manifested when one or more of the dimensions of a solid are reduced sufficiently. As such, in every case the wave function, energy levels, density of states, etc. will be presented and discussed. For quantum wells, several geometries will be considered (square, parabolic, and triangular). The particular case of strained layers and the effect of these particular layers on the electronic band structure will be also studied. Finally, excitonic effects in low-dimensional structures will be analyzed.
