Bistability between -diradical open-shell and closed-shell states in indeno[1,2-a]fluorene
Shantanu Mishra, Manuel Vilas-Varela, Leonard-Alexander Lieske +7
Indenofluorenes are non-benzenoid conjugated hydrocarbons that have received great interest owing to their unusual electronic structure and potential applications in non-linear opt…
Charge-state lifetimes of single molecules on ultrathin insulating films
Katharina Kaiser, Leonard-Alexander Lieske, Jascha Repp +1
In scanning tunneling microscopy (STM) experiments of molecules on insulating films, tunneling through molecular resonances implies transiently charging the molecule. The transitio…
Selectivity in single-molecule reactions by tip-induced redox chemistry
Florian Albrecht, Shadi Fatayer, Iago Pozo +4
Controlling selectivity of reactions is a quest in chemistry. Here, we demonstrate reversible and selective bond formation and dissociation promoted by tip-induced reduction-oxidat…
Non-benzenoid high-spin polycyclic hydrocarbons generated by atom manipulation
Shantanu Mishra, Shadi Fatayer, Saleta Fernandez +3
We report the on-surface synthesis of a non-benzenoid triradical through dehydrogenation of truxene (C27H18) on coinage metal and insulator surfaces. Voltage pulses applied via the…
Probing molecular excited states by atomic force microscopy
Shadi Fatayer, Florian Albrecht, Ivano Tavernelli +3
By employing single charge injections with an atomic force microscope, we investigated redox reactions of a molecule on a multilayer insulating film. First, we charged the molecule…
An sp-hybridized molecular carbon allotrope, cyclo[18]carbon
Katharina Kaiser, Lorel M. Scriven, Fabian Schulz +3
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 structura…
Molecular structure elucidation with charge-state control
Shadi Fatayer, Florian Albrecht, Yunlong Zhang +4
The charge state of a molecule governs its physicochemical properties, such as conformation, reactivity and aromaticity, with implications for on-surface synthesis, catalysis, phot…
Passivation of dangling bonds on hydrogenated Si(100)-21: a possible method for error correction in hydrogen lithography
Niko Pavliček, Zsolt Majzik, Gerhard Meyer +1
Using combined low temperature scanning tunneling microscopy (STM) and atomic force microscopy (AFM), we demonstrate hydrogen passivation of individual, selected dangling bonds (DB…
Atomic and Electronic Structure of Si Dangling Bonds in Quasi-Free-Standing Monolayer Graphene
Yuya Murata, Tommaso Cavallucci, Valentina Tozzini +7
Si dangling bonds without H termination at the interface of quasi-free standing monolayer graphene (QFMLG) are known scattering centers that can severely affect carrier mobility. I…
Interactions between two C60 molecules measured by scanning probe microscopies
Nadine Hauptmann, César González, Fabian Mohn +3
C60-functionalized tips are used to probe C60 molecules on Cu(111) with scanning tunneling and atomic force microscopy. Distinct and complex intramolecular contrasts are found. Max…
Effect of electron-phonon interaction on the formation of one-dimensional electronic states in coupled Cl vacancies
Bruno Schuler, Mats Persson, Sami Paavilainen +4
The formation of extended electron states in one-dimensional nanostructures is of key importance for the function of molecular electronics devices. Here we study the effects of str…
Investigating Atomic Contrast in Atomic Force Microscopy and Kelvin Probe Force Microscopy on Ionic Systems using Functionalized Tips
Leo Gross, Bruno Schuler, Fabian Mohn +7
Noncontact atomic force microscopy (NC-AFM) and Kelvin probe force microscopy (KPFM) have become important tools for nanotechnology; however, their contrast mechanisms on the atomi…
Force and Conductance during contact formation to a C60 molecule
Nadine Hauptmann, Fabian Mohn, Leo Gross +3
Force and conductance were simultaneously measured during the formation of Cu-C60 and C60-C60 contacts using a combined cryogenic scanning tunneling and atomic force microscope. Th…
Temperature dependence of the nonlocal voltage in an Fe/GaAs electrical spin injection device
G. Salis, A. Fuhrer, R. R. Schlittler +2
The nonlocal spin resistance is measured as a function of temperature in a Fe/GaAs spin-injection device. For nonannealed samples that show minority-spin injection, the spin resist…
