High-Resolution Near-Field Optical Investigation of Crystalline Domains in Oligomeric PQT-12 Thin Films

Autor: Markus Breusing, Thomas Fischer, Dieter Neher, Patrick Pingel, Sergei Kuehn, Joachim Stumpe, Thomas Elsaesser

Publikováno v: Advanced Functional Materials. 21:860-868

The structure and morphology on different length scales dictate both the electrical and optical properties of organic semiconductor thin fi lms. Using a combination of spectroscopic methods, including scanning near-fi eld optical microscopy, we study

Ultrafast nonequilibrium carrier dynamics in a single graphene layer

Autor: Markus Breusing, Ermin Malic, Andreas Knorr, Claus Ropers, Thomas Elsaesser, Frank Milde, Sergei Kuehn, Jürgen P. Rabe, Nikolai Severin, Torben Winzer

Publikováno v: Physical Review B. 83

Nonequilibrium carrier dynamics in single exfoliated graphene layers on muscovite substrates are studied by ultrafast optical pump-probe spectroscopy and compared with microscopic theory. The very high 10-fs-time resolution allows for mapping the ult

Journal of Applied Physics, 108 . 043107-043107. ISSN 0021-8979

Multiphoton-absorption (MPA) induced ultraviolet (UV) luminescence of ZnO nanorods grown by vapor phase transport was demonstrated using ultrafast excitation at pulse energies in the few nanojoules range, directly generated by a Ti:sapphire laser osc

Ultrafast carrier dynamics in graphite

Autor: Thomas Elsaesser, Markus Breusing, Claus Ropers

Publikováno v: Physical review letters. 102(8)

Optical pump-probe spectroscopy with 7-fs pump pulses and a probe spectrum wider than 0.7 eV reveals the ultrafast carrier dynamics in freestanding thin graphite films. We discern for the first time a rapid intraband carrier equilibration within 30 f

In situ scanning tunneling microscopy during metal-organic vapor phase epitaxy

Autor: Wolfgang Richter, Markus Breusing, Markus Pristovsek, Raimund Kremzow, Bert Rähmer

Publikováno v: Applied Physics Letters. 89:063108

The authors report the first ever in situ scanning tunnelling microscopy measurements in metal-organic vapor phase epitaxy (MOVPE) using an active cooling shield for operation up to 650°C. Apart from fundamental considerations and constraints, some
