We propose a simple procedure that restores the ionization potential theorem as the sole tuning criterion for both the long- and short-range Fock exchange of the range-separated hybrid functional. The procedure works by screening out an opposing effe

The process of introducing extra charge carriers into organic semiconductors, or simply molecular doping, takes place via intermolecular charge transfer from the donor to the acceptor molecule. Using density functional theory calculations on diverse

Sulflower, a thiophene-based circulene, is a well-rounded candidate for hole transport with no experimental data so far living up to theoretical predictions. By calculating the band structure on its single crystal using density functional theory meth

At metal/organic interfaces, the insertion of an or- ganic monolayer can significantly modify the surface proper- ties of the substrate, especially in terms of charge injection across the interface. Herein, we study the formation of an insulating mon

The design of new organic molecules with the first triplet ( T 1 ) excitation energy high enough for use as host materials for blue phosphorescence is challenging because the energy transfer from host to guest requires the host to have a T 1 energy g

A Ni 2 P/SiO 2 catalyst was prepared by temperature-programed reduction (TPR), and applied for the hydrodeoxygenation of guaiacol. The physical properties of the catalyst samples were characterized by N 2 adsorption/desorption isotherms and CO uptake

We propose a new structural model for the Al(1 1 1)/Al 2 O 3 (0 0 0 1) interface based on density functional theory calculations. The ultrathin interface structure is shown to consist of two Al layers, one that is oxide-like and the other metal-like.
