Silicene is a new form of Silicon, first presented by physicist Guy Le Lay at American Physics Society march 2011 meeting in Dallas, Texas. Le Lay had grown sheets of honeycombed silicon with layers just one atom thick.
Structurally, Silicene looks a lot like graphene, which is also a honeycombed sheet, but of carbon atoms rather than silicon.
Silicene has attractive and trendy properties like:
* Its 2-D Structure leads to strange quantum effects and allow electrons to streak across it at incredible speed - properties to develop electronic devices.
* It has characteristics similar to topological insulators - material that conduct electrons only on their outer surfaces.
Problems associated with silicene are:
* Silicene is super-sticky. Graphene is a stable material but Silicene reacts easily with the environment - oxidizing in the air and bonding chemically with other materials.
* Silicene's reactivity makes it much harder to produce than Graphene.
Remedies :
* Only two materials have been found to support Silicene up to now. One, Zirconium diboride, has the advantage of naturally sucking silicene onto its surface from a block of silicon positioned below. The other is crystalline iridium.
Applications :
* To manufacture electronic devices with high conductivity & minimal thickness.
