Growth of an Ordered Crystalline Organic Heterojunction**
Organic semiconductors have gained tremendous attention over the last two decades due to their potential for use in thin film transistors (TFTs), sensors, solar cells and organic light emitting diodes The best device performances (particularly for TFTs) have often been achieved using free standing single crystals. However, in general the size, thickness, and shape of such crystals are not easil...
متن کاملCrystalline structure-dependent growth of bimetallic nanostructures.
Morphological control of multimetallic nanostructures is crucial for obtaining shape-dependent physical and chemical properties. Up to date, control of the shapes of multimetallic nanostructures has remained largely empirical. Multimetallic nanostructures have been produced mostly through seed-mediated growth. Understanding the role played by starting nanocrystal seeds can help in controlling t...
متن کاملEffects of crystalline microstructure on epitaxial growth.
The results of kinetic Monte Carlo simulations of epitaxial growth on fcc~100! and bcc~100! surfaces in which the correct crystal geometry is taken into account are reported. The existence of downward funneling to fourfold hollow sites leads to a downward current for large angles and to angle selection as observed in a variety of experiments. We have used our model to simulate Fe/Fe~100! deposi...
متن کاملGrowth of randomly oriented single-crystalline tin (IV) oxide nanobelts: control on the predominant crystalline growth axis.
One-dimensional nanobelts of tin (IV) oxide are synthesized by using a newly introduced catalyst-assisted pulsed laser deposition method along two growth directions of [010] and [101]. An ex situ mask-induced growth gradient technique is employed to investigate the growth evolution of the nanobelts on oxidized-Si, H-terminated Si, and Al2O3(0001) substrates by helium ion microscopy, which revea...
متن کاملGrowth and modelling of spherical crystalline morphologies of molecular materials.
Crystalline, yet smooth, sphere-like morphologies of small molecular compounds are desirable in a wide range of applications but are very challenging to obtain using common growth techniques, where either amorphous films or faceted crystallites are the norm. Here we show solvent-free, guard flow-assisted organic vapour jet printing of non-faceted, crystalline microspheroids of archetypal small ...
