Which is a semiconductor fullerene?

Fullerene is a spherical carbon compound and is an allotrope of carbon such as diamond, graphite and carbon nanotubes. Fullerenes of C60, C70 and C84 are well known. Any fullerenes are n-type semiconductors, which are suitable for organic electronic materials with electron carriers. …

What is a fullerene easy definition?

Fullerene, also called buckminsterfullerene, any of a series of hollow carbon molecules that form either a closed cage (“buckyballs”) or a cylinder (carbon “nanotubes”).

What is C70 fullerene used for?

Fullerenes can be used as organic photovoltaics(OPV), these are powerful antioxidants, reacting readily and at a high rate with free radicals which are often the cause of cell damage or death. Other uses of C70 like catalysts, in water purification and biohazard protection, portable power, vehicles and medical.

How many carbon atoms are in C70 fullerene?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) C70 fullerene is the fullerene molecule consisting of 70 carbon atoms.

Which is the best description of a fullerene?

fullerene – a form of carbon having a large molecule consisting of an empty cage of sixty or more carbon atoms. chemical science, chemistry – the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions.

What kind of molecule is C 60 fullerite?

C 60 fullerite (bulk solid C 60 ). A fullerene is an allotrope of carbon whose molecule consists of carbon atoms connected by single and double bonds so as to form a closed or partially closed mesh, with fused rings of five to seven atoms. The molecule may be a hollow sphere, ellipsoid, tube, or many other shapes and sizes.

What is the bandgap of C 70 fullerene?

C 70 forms brownish crystals with a bandgap of 1.77 eV. It is an n-type semiconductor where conductivity is attributed to oxygen diffusion into the solid from atmosphere. The unit cell of fcc C 70 solid contains voids at 4 octahedral and 12 tetrahedral sites. They are large enough to accommodate impurity atoms.
