Journal ArticleDOI

Generalized Kohn-Sham schemes and the band-gap problem

TL;DR: The corresponding generalized Kohn-Sham eigenvalue gaps are shown to incorporate part of the discontinuity D xc of the exchange-correlation potential of standard KohnSham theory, leading to band gaps far better than those of local-density approximation.
Journal ArticleDOI

Pyroelectric properties of Al(In)GaN/GaN hetero- and quantum well structures

TL;DR: In this paper, it was shown that the macroscopic nonlinear pyroelectric polarization of wurtzite AlInN/GaN, InxGa1-xN and AlxIn1xN ternary compounds (large spontaneous polarization and piezoelectric coupling) dramatically affects the optical and electrical properties of multilayered Al(In)GaN/GAN hetero-, nanostructures and devices, due to the huge built-in electrostatic fields and bound interface charges caused by gradients in polarization at surfaces and heter
Journal ArticleDOI

Exact exchange Kohn-Sham formalism applied to semiconductors

TL;DR: In this paper, the Kohn-Sham method is used to calculate lattice constants, cohesive energies, Kohn Sham eigenvalues, dielectric functions, and effective masses of various zinc-blende semiconductors (Si, Ge, C, SiC, GaAs, AlAs, GaN, and AlN).
Journal ArticleDOI

Exact Kohn-Sham Exchange Potential in Semiconductors

TL;DR: In this paper, a new Kohn-Sham method that treats exchange interactions within density functional theory exactly is applied to Si, diamond, GaN, and InN and shows that the exchange contribution to the derivative discontinuity of the exchange-correlation potential is very large (of the order of 5-10 eV).
Journal ArticleDOI

Post-anaesthesia pulmonary complications after use of muscle relaxants (POPULAR): a multicentre, prospective observational study.

Eva Kirmeier, +865 more
TL;DR: It is shown that the use of neuromuscular blocking drugs in general anaesthesia is associated with an increased risk of postoperative pulmonary complications, and Anaesthetists must balance the potential benefits of neurmuscular blockade against the increasedrisk of postoperatively pulmonary complications.
