Ekici E, Kapitza P, Bobisch C, Moller R
Opt Lett . 2017 Nov; 42(22):4585-4588. PMID: 29140318
The light emission from a tunneling junction induced by tunneling electrons has been studied around the cutoff at hν=eV. The emitted photons are found to exceed the excitation energy provided...

Bauer S, Bobisch C
J Phys Condens Matter . 2017 Jun; 29(33):334002. PMID: 28628028
We analyse the electron transport in a 16 quintuple layer thick stepped BiSe film grown on Si(1 1 1) by means of scanning tunnelling potentiometry (STP) and multi-point probe measurements....

Wortmann B, van Vorden D, Graf P, Robles R, Abufager P, Lorente N, et al.
Nano Lett . 2015 Dec; 16(1):528-33. PMID: 26645498
We report on a reversible structural phase transition of a two-dimensional system that can be locally induced by an external electric field. Two different structural configurations may coexist within a...

van Vorden D, Lange M, Schmuck M, Schaffert J, Cottin M, Bobisch C, et al.
J Chem Phys . 2013 Jun; 138(21):211102. PMID: 23758351
Individual molecules of octa-ethyl-porhphyrin-iron(III)-chloride adsorbed on a Cu(111) surface are studied by scanning tunneling microscopy. Upon moderate heating the molecules are found to transform into Fe-tetra-benzo-porphyrin at a surprisingly low...

Schaffert J, Cottin M, Sonntag A, Karacuban H, Utzat D, Bobisch C, et al.
Rev Sci Instrum . 2013 May; 84(4):043702. PMID: 23635198
The paper describes a simple scheme enabling the real-time characterization of fluctuations, e.g., of the conductance in scanning tunneling microscopy. The technique can be used in parallel to other data...

Kaspers M, Bernhart A, Bobisch C, Moller R
Nanotechnology . 2012 May; 23(20):205706. PMID: 22543691
Scanning tunnelling microscopy was used to study the morphological changes of the surface of a single-crystalline silver nanowire caused by a lateral electron current. At current densities of about 1.5...

Bannani A, Bobisch C, Matena M, Moller R
Nanotechnology . 2011 Aug; 19(37):375706. PMID: 21832560
In this work we report on ballistic electron emission spectroscopy (BEES) studies on epitaxial layers of silver grown on silicon surfaces, with either a Si(111)-(7  × 7) or Si(100)-(2  × ...

Phys Rev Lett . 2011 Jan; 105(21):217402. PMID: 21231352
We report the spatial imaging of the photon transition probability of a single molecule at submolecular resolution. Photon imaging of a ringlike pattern is further resolved as two orthogonal vibronic...

Science . 2009 Aug; 325(5943):981-5. PMID: 19696347
Atomic-scale spatial imaging of one-dimensional chains of silver atoms allows Fermi's golden rule, a fundamental principle governing optical transitions, to be visualized. We used a scanning tunneling microscope (STM) to...

Bobisch C, Bannani A, Koroteev Y, Bihlmayer G, Chulkov E, Moller R
Phys Rev Lett . 2009 Apr; 102(13):136807. PMID: 19392390
We report on ballistic electron emission microscopy and spectroscopy studies on epitaxial (3-5 nm thick) Bi(111) films, grown on n-type Si substrates. The effective barrier heights of the Schottky barrier...
