Negative differential conductance in triangular molecular assemblies
Chao Li, Vladislav Pokorný, Prokop Hapala +7
We report the creation and characterization of a molecular-scale negative differential conductance (NDC) device by assembling a triangular trimer of 4,5,9,10-tetrabromo-1,3,6,8-tet…
Advancing Scanning Probe Microscopy Simulations: A Decade of Development in Probe-Particle Models
Niko Oinonen, Aliaksandr V. Yakutovich, Aurelio Gallardo +3
The Probe-Particle Model combine theories designed for the simulation of scanning probe microscopy experiments, employing non-reactive, flexible tip apices to achieve sub-molecular…
Evidence of trion-libron coupling in chirally adsorbed single molecules
Jiří Doležal, Sofia Canola, Prokop Hapala +3
Interplay between motion of nuclei and excited electrons in molecules plays a key role both in biological and artificial nanomachines. Here we provide a detailed analysis of coupli…
Computational study of radiative rate in silicon nanocrystals: Role of electronegative ligands and tensile strain
Katerina Dohnalova Newell, Prokop Hapala, Katerina Kusova +1
It is widely accepted that the properties of most semiconductor nanocrystals can be tuned by their core size, shape and material. In covalent semiconductor nanocrystal materials, s…
Iron-based trinuclear metal-organic nanostructures on a surface with local charge accumulation
Cornelius Krull, Marina Castelli, Prokop Hapala +3
Coordination chemistry relies on harnessing active metal sites within organic matrices. Polynuclear complexes - consisting of organic ligands binding to clusters of several metal a…
Principles and simulations of high-resolution STM imaging with flexible tip apex
O. Krejci, P. Hapala, M. Ondracek +1
We present a robust but still efficient simulation approach for high-resolution scanning tunneling microscopy with a flexible tip apex showing sharp submolecular features. The appr…
