Excitons and Two-dimensional Screening: Critical Screening Lengths
Christian Tanguy
A beautiful and intriguing relationship has recently been proposed to express the critical screening lengths associated with the apparition of new bound states for the two-dimensio…
Bosonic behavior of excitons and screening: a consistent calculation
Christian Tanguy
Excitons have recently been shown to deviate from pure bosons at densities a hundred times smaller than the Mott density. The corresponding calculations relied on the unscreened ex…
Counting the Number of Bound States of Two-dimensional Screened Coulomb Potentials: A Semiclassical Approach
Christian Tanguy
Portnoi and Galbraith recently proposed a beautiful and intriguing relationship defining the critical screening lengths associated with the apparition of new bound states for the t…
New criteria for bosonic behavior of excitons
Monique Combescot, Christian Tanguy
Dimensional arguments lead to say that excitons in a sample of volume behave as bosons for , being the exciton radius and a dimensionless factor…
