Experimental and theoretical investigations have revealed that the chemical and physical
properties of graphene are crucially determined by their topological structures. Therefore …

Transport of electrons in a single molecule junction is the simplest problem in the general
subject area of molecular electronics. In the past few years, this area has been extended to …

Carbon allotropes built from rings of two-coordinate atoms, known as cyclo [n] carbons, have
fascinated chemists for many years, but until now they could not be isolated or structurally …

Topological materials exhibit protected edge modes that have been proposed for
applications in, for example, spintronics and quantum computation. Although a number of …

The formation of excitons in organic molecules by charge injection is an essential process in
organic light-emitting diodes (OLEDs),,,,,–. According to a simple model based on spin …

Structural defects in 2D materials offer an effective way to engineer new material
functionalities beyond conventional doping. We report on the direct experimental correlation …

In molecular tunnel junctions, where the molecule is decoupled from the electrodes by few-
monolayers-thin insulating layers, resonant charge transport takes place by sequential …

The bistability in the position of the two hydrogen atoms in the inner cavity of single free-
base naphthalocyanine molecules constitutes a two-level system that was manipulated and …

Using scanning probe microscopy techniques, at low temperatures and in ultrahigh vacuum,
individual molecules adsorbed on surfaces can be probed with ultrahigh resolution to …

Defects play a key role in determining the properties and technological applications of
nanoscale materials and, because they tend to be highly localized, characterizing them at …
