“…Some physical properties can be significantly affected during the horizontal expansion of the islands. For example, tilting of crystallographic orientation has frequently been observed in epitaxial layers [8][9][10], and it was speculated that this tilting resulted from the effects of interfacial tensions. In this Letter we report on an unusual crystallization behavior of NH 4 Cl on a glass substrate.…”

Consecutive Rotation of Crystallographic Orientation in Lateral Growth

A consecutive rotation of crystallographic orientation has been observed in lateral crystallization of NH4Cl on a glass substrate, which induces a periodic distribution of faceted and roughened regions on the surface of a crystallite aggregate. Experimental observation indicates that this phenomenon derives from the asymmetric surface energies at the growth front, which deform the nascent nucleus and tilt the crystallographic orientation in the nucleation-mediated layered growth. We suggest that this effect is significant for a class of lateral growth where nucleation plays a dominate role.

“…[805], were fabricated using the pulsed-laser-deposition (PLD) method, which was developed earlier for the epitaxial growth of high T c copper oxides [806]. The stoichiometry and morphology of the deposited thin films was shown [805,807,808] to depend on the thermodynamic conditions during growth (temperature of substrat, nature of substrat, oxygen pressure and deposition rate). The thin films are granular with the largest grains when grown at high T (350 • C < T < 500 • C) and low deposition rate.…”

This article reviews the static and dynamic properties of spontaneous superstructures formed by electrons. Representations of such electronic crystals are charge density waves and spin density waves in inorganic as well as organic low dimensional materials. A special attention is paid to the collective effects in pinning and sliding of these superstructures, and the glassy properties at low temperature. Charge order and charge disproportionation which occur in organic materials resulting from correlation effects are analysed. Experiments under magnetic field, and more specifically field-induced charge density waves are discussed. Properties of meso-and nanostructures of charge density waves are also reviewed.

“…Based upon previous experience [14][15][16] with the structurally very similar compound Rb 0.3 MoO 3 , oxygen pressure (p O2 ) has been varied between 1 and 10 Pa and the substrate temperature (T S ) between 400 C and 450 C with several attempts at 350 C and 500 C. Depositions for each set of conditions were performed on both (510)SrTiO 3 (STO) and (1-102)Al 2 O 3 (ALO) substrates, which have suitable lattice parameters. 14 The laser pulse parameters have been kept constant at 248 nm wavelength and 25 ns pulse width, with repetition rate of 5 Hz and pulse energy of 250 mJ corresponding to a fluence of 2.4 J/cm 2 .…”

“…Van der Zant et al have successfully applied the pulsed laser deposition (PLD) technique [14][15][16][17][18] to grow films of CDW system Rb 0.3 MoO 3 with thickness of the order of 1 lm. However, for the time-resolved THz conductivity measurements, as well as for FED experiments, the films should be about one order of magnitude thinner.…”

During the last years, femtosecond time-resolved spectroscopy (fsTRS) has become an important new tool to investigate low energy excitations in strongly correlated systems. By studying energy relaxation pathways linking various degrees of freedom (e.g., electrons, spin, or lattice), the interaction strengths between different subsystems can be deduced. Here we report on yet another application of fsTRS, where the technique is used to unambiguously determine the nature of the ground state in granular thin films of a prototype charge density wave system blue bronze, K0.3MoO3. These, potassium blue bronze, films, obtained for the first time ever, have been prepared by pulsed laser deposition and investigated by various standard characterization methods. While the results of all used methods indicate that the thin films consist of nanometer grains of K0.3MoO3, it is only the non-destructive fsTRS that demonstrates the charge density wave nature of the ground state. Furthermore, the comparison of the fsTRS data obtained in thin films and in single crystals shows the reduction of the charge density wave transition temperature and of the photoinduced signal strength in granular thin films in respect to single crystals, which is attributed to the granularity and crystal growth morphology.
