Figure 2 shows the energy band diagram of a direct bandgap semiconductor where EƔ is lower in energy than EX, and spontaneous emission of a photon is the most likely path for recombination. In Fig. 2, the Ɣ valley of the conduction band is directly above the holes where the momentum...

We reconsider model II of Orban et al. (J. Chem. Phys. 1968, 49, 1778–1783), a two-dimensional lattice-gas system featuring a crystalline phase and two distinct fluid phases (liquid and vapor). In this system, a particle prevents other particles from occupying sites up to third neighbor...
