Examples of nanowires include inorganic molecular nanowires (Mo 6 S 9−x I x, Li 2 Mo 6 Se 6), which can have a diameter of 0.9 nm and be hundreds of micrometers long. Other important examples are based on semiconductors such as InP, Si, GaN, etc., dielectrics (e.g. SiO 2 ,TiO 2 ), or metals (e.g. Ni, Pt).
Most types of molecular wires are derived from organic molecules. One naturally occurring molecular wire is DNA.Prominent inorganic examples include polymeric materials such as Li 2 Mo 6 Se 6 [1] and Mo 6 S 9−x I x, [2] [3] [4] [Pd 4 (CO) 4 (OAc) 4 Pd(acac) 2], [5] and single-molecule extended metal atom chains (EMACs) which comprise strings of transition metal atoms directly bonded to each ...
2-Carboxybenzaldehyde is a chemical compound.It consists of a benzene ring, with an aldehyde and a carboxylic acid as substituents that are ortho to each other. The compound exhibits ring–chain tautomerism: the two substituents can react with each other to form 3-hydroxyphthalide, a cyclic lactol.
Potassium niobate (KNbO 3) is an inorganic compound with the formula KNbO 3. A colorless solid, it is classified as a perovskite ferroelectric material. [2] It exhibits nonlinear optical properties, and is a component of some lasers. [3] Nanowires of potassium niobate have been used to produce tunable coherent light.

Nanowires of CsPbBr 3, on the other hand, emit from 473 nm to 524 nm depending on the width of the wire prepared with lifetimes also in the range of 2.5 ns – 20.6 ns. [ 111 ] Similarly to CsPbBr 3 , MAPbBr 3 NCs also exhibit morphologically dependent optical properties with nanocrystals of MAPbBr 3 emitting from 475 nm to 520 nm [ 112 ] and ...
Silicon nanowires exhibit a distinct and useful self-limiting oxidation behaviour whereby oxidation effectively ceases due to diffusion limitations, which can be modeled. [1] This phenomenon allows accurate control of dimensions and aspect ratios in SiNWs and has been used to obtain high aspect ratio SiNWs with diameters below 5 nm. [ 19 ]
One-dimensional crystalline nanowires are then grown by a liquid metal-alloy droplet-catalyzed chemical or physical vapor deposition process, which takes place in a vacuum deposition system. Au-Si droplets on the surface of the substrate act to lower the activation energy of normal vapor-solid growth.
