Achieving Predictive Description of Negative Differential Resistance in Molecular Junctions Using a Range-Separated Hybrid Functional
(Wiley-VCH Verlag, 2021)Range-separated hybrid (RSH) functionals have been recently used to overcome the tendency of traditional density functional theory (DFT) calculations to overestimate the conductance of molecular junctions. Non-equilibrium ... -
Applicability of noninteger bessel type orbital basis sets: numerical and analytical approaches
