Screening in semiconductor nanocrystals: \textit{Ab initio} results and Thomas-Fermi theory
F. Trani, D. Ninno, G. Cantele +4
A first-principles calculation of the impurity screening in Si and Ge nanocrystals is presented. We show that isocoric screening gives results in agreement with both the linear res…
Ab initio calculations of electron affinity and ionization potential of carbon nanotubes
F. Buonocore, F. Trani, D. Ninno +3
By combining ab initio all-electron localized orbital and pseudopotential plane-wave approaches we report on calculations of the electron affinity (EA) and the ionization potential…
Role of local fields in the optical properties of silicon nanocrystals using the tight binding approach
F. Trani, D. Ninno, G. Iadonisi
The role of local fields in the optical response of silicon nanocrystals is analyzed using a tight binding approach. Our calculations show that, at variance with bulk silicon, loca…
Formation of polaron clusters
C. A. Perroni, G. Iadonisi, V. K. Mukhomorov
The formation of spherical polaron clusters is studied within the Frhlich polaron theory. In a dilute polaron gas, using the non-local statistical approach and the polaro…
Modelling of strain effects in manganite films
C. A. Perroni, V. Cataudella, G. De Filippis +3
Thickness dependence and strain effects in films of perovskites are analyzed in the colossal magnetoresistance regime. The calculations are based on a generaliza…
Infrared conductivity of a one-dimensional charge-ordered state: quantum lattice effects
C. A. Perroni, V. Cataudella, G. De Filippis +3
The optical properties of the charge-ordering () phase of the one-dimensional (1D) half-filled spinless Holstein model are derived at zero temperature within a well-known varia…
