Ultrafast carrier kinetics in exfoliated graphene and thin graphite films.

Time-resolved transmissivity and reflectivity of exfoliated graphene and thin graphite films on a 295 K SiO(2)/Si substrate are measured at 1300 nm following excitation by 150 fs, 800 nm pump pulses. From the extracted transient optical conductivity we identify a fast recovery time constant which increases from approximately 200 to 300 fs and a longer one which increases from 2.5 to 5 ps as the...

Simple metal under tensile stress: layer-dependent herringbone reconstruction of thin potassium films on graphite

While understanding the properties of materials under stress is fundamentally important, designing experiments to probe the effects of large tensile stress is difficult. Here tensile stress is created in thin films of potassium (up to 4 atomic layers) by epitaxial growth on a rigid support, graphite. We find that this "simple" metal shows a long-range, periodic "herringbone" reconstruction, obs...

The Surface Structure of Ultra-Thin P(VDF-TrFE) Copolymer Films on Graphite

The structure and local structural distortions, through the polarization manipulation, of crystalline films of ferroelectric vinylidene fluoride (70%) with trifluoroethylene (30%) [P(VDF-TrFE)] copolymer on graphite were studied by scanning tunneling microscopy (STM). A quasi-spiral twist in C-C bonds with rotations about the polymer chain axis was observed by high-resolution STM, indicating a ...
