We review recent work on organic molecular beam deposition (OMBD) with emphasis on
growth studies beyond the first monolayer, ie the evolution of the film structure and …

Just as biological synapses provide basic functions for the nervous system, artificial synaptic
devices serve as the fundamental building blocks of neuromorphic networks; thus …

The present status of development of the density-functional-based tight-binding (DFTB)
method is reviewed. As a two-centre approach to density-functional theory (DFT), it …

The band shapes corresponding to both the absorption and emission spectra of a set of 20
representative conjugated molecules, including recently synthesized structures, have been …

The Self-consistent charge density functional tight-binding (SCC-DFTB) is an approximate
quantum chemical method derived from density functional theory (DFT) based on a second …

The functional dependence of excited-state geometries and normal modes calculated with
time-dependent density functional theory (TDDFT) is investigated on the basis of vibronic …

We consider the exciton states in quasi-one-dimensional organic crystals with strong orbital
overlap between neighboring molecules. In such crystals, the energy difference between the …

Recent experiments on the electronic spectroscopy of atoms, clusters, and organic
molecules embedded in helium nanodroplets are reviewed. Electronic transitions imply a …

Despite the recent advances in bottom-up synthesis of different kinds of atomically precise
graphene nanoribbons (GNRs) with very diverse physical properties, the translation of these …

The diimide perylene motif exhibits a dramatic intensity reversal between the 0→ 0 and 0→
1 vibronic bands upon π− π stacking; this distinct spectral property has previously been …
