Condensation of excitons and the spectrum of multiparticle states in SiGe/Si quantum wells: The role of the barrier in the conduction band
It has been demonstrated that the barrier in the conduction band represented by the SiGe layer in SiGe/Si quantum wells affects the work function and equilibrium density of the quasi-two-dimensional condensed phase formed in these structures. The existence of a new recombination channel with unconve...

| description | It has been demonstrated that the barrier in the conduction band represented by the SiGe layer in SiGe/Si quantum wells affects the work function and equilibrium density of the quasi-two-dimensional condensed phase formed in these structures. The existence of a new recombination channel with unconventional characteristics is uncovered in the structures with barrier heights close to the critical value for the formation of the electron-hole liquid. |
