• transport between the contacts. A beneficial effect was demonstrated for the structurally identical Sb2Se3 [9]. A proper substrate choice or embedding a seed layer might be the key to directed growth in Sb2S3. Experimental Chemicals: All chemicals were purchased from Sigma-Aldrich except for KP115 which was

• toxicity or biocompatibility of nanoparticles is an extremely important consideration for many of the aforementioned proposed applications. In particular carbon nanotubes, commonly used in applications such as drug delivery [10] and directed growth of neuron cells [11], have been shown to exhibit

In other words, a directed growth of NaCl crystals emerging as, for example, a fibrillar structure may explain these stronger-than-expected

• Abstract The growth of molecular assemblies at room temperature on insulating surfaces is one of the main goals in the field of molecular electronics. Recently, the directed growth of porphyrin-based molecular wires on KBr(001) was presented. The molecule–surface interaction associated with a strong dipole

• molecular assemblies can be formed. The electronic decoupling of the molecules by one or two monolayers of KBr from the Cu(111) substrate is found to be insufficient to enable comparable growth conditions to bulk ionic materials. Keywords: directed growth; KBr; molecular wires; NaCl; nc-AFM; porphyrin

• measurements of molecules on insulating surfaces were scarce due to a lack of suitable imaging techniques. However, recent progress in high resolution nc-AFM has given the opportunity to verify the proposed concept of directed growth of molecular wires on insulators [31][32][33]. Alkali halides offer some
