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 ...
Having the same stoichiometric chemical formula, α-Bi 4 I 4 and β-Bi 4 I 4 show similar solid-state structures yet critically different physicochemical properties. [8] Specifically, α-Bi 4 I 4 represents the trivial insulator phase, while stacking of the bismuth atoms along the b crystallographic axis in the β-Bi 4 I 4 phase yield a ...
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.

Digermane has a limited number of applications; germane itself is the preferred volatile germanium hydride. Generally, digermane is primarily used a precursor to germanium for use in various applications. Digermane can be used to deposit Ge-containing semiconductors via chemical vapor deposition. [12]
Nanowires and nanotubes: The elastic moduli of some nanowires namely lead and silver, decrease with increasing diameter. This has been associated with surface stress, oxidation layer, and surface roughness. [62] However, the elastic behavior of ZnO nanowires does not get affected by surface effects but their fracture properties do.
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.
