Copolymers with similar comonomers: Tuning frontier orbital energies for application in organic solar cells
(2016-04-01)
Today, there is an intense search for new electron donor polymers for the active layers of organic solar cells. The synthesis of copolymers, in which there is a mix of electron donor monomers with others that are electron ...
Is the decrease of the total electron energy density a covalence indicator in hydrogen and halogen bonds?
(Springer, 2013-05)
In this work, halogen bonding (XB) and hydrogen bonding (HB) complexes were studied with the aim of analyzing the variation of the total electronic energy density H(rb) with the interaction strengthening. The calculations ...
Pauli nonlocality in heavy-ion rainbow scattering: A further test of the folding model
(1997-12-01)
Nonlocal interactions are an intrinsically quantum phenomenon. In this work we point out that, in the context of heavy ions, such interactions can be studied through the refractive elastic scattering of these systems at ...

Electronic structure of first and second row atoms under harmonic confinement
(Wiley, 2020)
Atoms under pressure undergo a number of modifications of their electronic structure. Good examples are the spontaneous ionization, stabilization of excited-state configurations, and contraction of atomic-shells. In this ...
Urbach energy parameter of flash evaporated amorphous gallium arsenide films
(2002-04-01)
The dependence of the optical absorption edge on the deposition crucible temperature is used to investigate the electronic states in As-rich a-GaAs flash evaporated films. The Urbach energy parameter, determined from ...
High-pressure assisted sintering of Ti-20Si-10B and Ti-10Si-5B powders
(2012-11-26)
This work presents the structural characterization of Ti-10Si-5B and Ti-20Si-10B (at-%) alloys produced by high-pressure assisted sintering. Sintering was performed in air at 1100 and 1200°C for 60 s using pressure levels ...
