Semiconductor Nanocrystals
5 February 2008The control in the chemical surface in any of the nanocrystalline structure depends on the fabrication device of the semiconductor nanocrystal. It has always been a desire to fabricate a nanomaterial that has a derivatized surface, however there are a few issues such as the chemical reactivity between the nanocrystal and another organic or inorganic group or the assembling methods to fabricate derivatized nanocrystal.
We have to find a suitable solution for above issues so that the functioning and integrity of semiconductor nanocrystals do not get disturbed. We can find out suitable inorganic, organic or mixture of organic and inorganic layer to get a derivatized surface so that the physical and chemical properties of semiconductor nanocrystals are enhanced. Various studies have been carried out using a number of surface passivators.
Researchers have established that the near band edge photoluminescence of the semiconductor can be enhanced by passivating the semiconductor with suitable chemicals.
